7. using the same information as given in (6), what is the probability that the sample mean will be within one standard deviation away from the mean in either the positive or negative direction?

Answers

Answer 1

Based on the information given in (6), we know that the mean is 65 and the standard deviation is 3. we can use the empirical rule to estimate the probability of the sample mean being within one standard deviation away from the mean in either the positive or negative direction.

According to the empirical rule, approximately 68% of the sample means will fall within one standard deviation away from the mean in either direction. Therefore, the probability of the sample mean being within one standard deviation away from the mean in either the positive or negative direction is approximately 0.68 or 68%.

The FDA regulates that fresh Albacore tuna fish contains at most 0.82 ppm of mercury. A scientist at the FDA believes the mean amount of mercury in tuna fish for a new company exceeds the ppm of mercury. A test statistic was found to be 2.576 and a critical value was found to be 1.645, what is the correct decision and summary

Answers

the test statistic is 2.576 and the critical value is 1.645.

Since the test statistic is greater than the critical value, we reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the mean amount of mercury in tuna fish for the new company exceeds 0.82 ppm.

To make a decision in this scenario, we need to use a hypothesis test. Let's set up the null and alternative hypotheses:

Null hypothesis (H0):

The mean amount of mercury in the tuna fish produced by the new company is less than or equal to 0.82 ppm.

Alternative hypothesis (Ha):

The mean amount of mercury in the tuna fish produced by the new company is greater than 0.82 ppm.

The test statistic is 2.576 and the critical value is 1.645.

Since the test statistic is greater than the critical value and is in the rejection region of the null hypothesis, we reject the null hypothesis.

we cannot say for certain whether this difference is statistically significant without knowing the sample size, the standard deviation of the sample, and the level of significance.

Reject the null hypothesis at the chosen significance level (which we don't have in this case), which suggests that the mean amount of mercury in the tuna fish produced by the new company is likely to be greater than 0.82 ppm.

This means that we have evidence to suggest that the mean amount of mercury in the tuna fish produced by the new company exceeds 0.82 ppm, as suspected by the scientist at the FDA.

Suppose your TA is applying to graduate schools. His chances to be admitted to each school are 5% and are the same for any school. How many different schools does he need to apply to if he wants his chance to be admitted to at least one school to be above 90%, 95%

Answers

We get x = 59. Therefore, your TA should apply to 59 schools to have a greater than 95% chance of being admitted to at least one school.

To calculate the number of different schools your TA needs to apply to in order to have a certain chance of being admitted to at least one school, we can use the formula:

n = log(1 - p) / log(1 - q)

Where n is the number of schools, p is the desired probability of being admitted to at least one school (i.e. 0.9 or 0.95), and q is the probability of not being admitted to any one school (i.e. 0.95).

Using this formula with p = 0.9 and q = 0.95, we get:

n = log(1 - 0.9) / log(1 - 0.05)
n ≈ 14

So your TA would need to apply to at least 14 different schools to have a chance of being admitted to at least one school above 90%.

Using the same formula with p = 0.95 and q = 0.95, we get:

n = log(1 - 0.95) / log(1 - 0.05)
n ≈ 29

So your TA would need to apply to at least 29 different schools to have a chance of being admitted to at least one school above 95%.
To determine the number of schools your TA needs to apply to in order to have at least a 90% and 95% chance of being admitted to at least one school, we'll use the concept of complementary probability.

Step 1: Calculate the probability of NOT being admitted to any school
The probability of not being admitted to a single school is 95% (100% - 5%).

Step 2: Use complementary probability to find the required probability
Let x be the number of schools your TA needs to apply to. The probability of not being admitted to any of the x schools is (0.95)^x.

Step 3: Find the number of schools for a 90% chance
We want the probability of being admitted to at least one school to be above 90%. Therefore, we want the complementary probability to be less than 10% (100% - 90%):
(0.95)^x < 0.10

Solving for x, we get x = 45. Therefore, your TA should apply to 45 schools to have a greater than 90% chance of being admitted to at least one school.

Step 4: Find the number of schools for a 95% chance
Similarly, for a 95% chance, we want the complementary probability to be less than 5% (100% - 95%):
(0.95)^x < 0.05

Solving for x, we get x = 59. Therefore, your TA should apply to 59 schools to have a greater than 95% chance of being admitted to at least one school.

Suppose that I have a sample of 25 women and they spend an average of $100 a week dining out, with a standard deviation of $20. The standard error of the mean for this sample is $4. Create a 95% confidence interval for the mean and wrap words around your results.

Answers

We can say with 95% confidence that the true mean amount that women in the population spend dining out per week lies within the range of $91.74 to $108.26.

Based on the given information, we can calculate a 95% confidence interval for the mean amount that women in the population spend dining out per week. With a sample size of 25 and a standard error of $4, we can use the formula:

95% CI = sample mean +/- (critical value x standard error)

To find the critical value, we need to look up the t-distribution with degrees of freedom (df) = n-1 = 24 and a significance level of alpha = 0.05/2 = 0.025 (since we are interested in a two-tailed test). From a t-table or calculator, we find that the critical t-value is approximately 2.064.

Plugging in the values, we get:

95% CI = $100 +/- (2.064 x $4)
95% CI = $100 +/- $8.26
95% CI = ($91.74, $108.26)

Therefore, we can say with 95% confidence that the true mean amount that women in the population spend dining out per week lies within the range of $91.74 to $108.26. This means that if we were to repeatedly take random samples of 25 women and calculate their mean amount spent dining out, about 95% of the intervals we construct using this method would contain the true population mean.

What is the probability that in a randomly selected composition of n has a second part and it is equal to 1

Answers

The probability of selecting a composition of n with a second part equal to 1 is equal to (n-1)/4.

Let us consider a composition of n as an ordered sequence of positive integers where the sum of the integers is n.

The number of compositions of n is equal to 2ⁿ⁻¹,

Since there are n-1 spaces between the numbers where we can choose to either include or exclude a separator.

To calculate the probability that a randomly selected composition of n has a second part equal to 1,

Consider the second part of the composition.

It can be any positive integer from 1 to n-1, inclusive.

For the second part to be equal to 1,

Choose 1 as the second number in the composition and distribute the remaining n-2 among the remaining slots.

There are n-1 slots left since the second slot is already occupied by the number 1.

The remaining n-2 can be distributed in 2ⁿ⁻³ ways, since there are n-3 spaces left to distribute the remaining numbers.

Therefore, the probability of selecting a composition of n with a second part equal to 1 is,

P = (n-1) ×  2ⁿ⁻³ / 2ⁿ⁻¹

  = ( n - 1 ) × 2ⁿ⁻³⁻ⁿ⁺¹

   =  ( n - 1 ) × 2⁻²

  = (n-1) / 4

Therefore, the probability is equal to  (n-1)/4.

Answers

The dimensions of the rectangular box are height = 7 ft, width = 28 ft, and length = 112 ft.

Let the height of the box be h. Then, the width is 4h, and the length is 16h. We know that the volume of the box is 343 ft³, so we can set up the equation: V = l*w*h = (16h)(4h)(h) = 64h³

64h³ = 343

h³ = 343/64 = 27/4

h = (27/4)^(1/3) = 3/2

So the height of the box is 3/2 ft. Using this value, we can find the width and length:

Width = 4h = 4(3/2) = 6 ft

Length = 16h = 16(3/2) = 24 ft

Answers

In the original Milgram experiment, only men participated, and the study aimed to investigate their obedience to authority figures. Later, a version of the experiment was conducted with only women participants to compare their obedience levels to men's.

In the replication of the Milgram experiment with only women participants, the level of obedience was found to be similar to that of the original experiment with only men. In fact, the results showed that women were just as likely as men to obey authority figures and administer the maximum level of electric shocks to the supposed "learner" in the experiment. This suggests that obedience to authority is not gender-specific and that both men and women can be equally susceptible to obeying orders, even when they conflict with their own moral beliefs.

To answer your question, women's obedience in the Milgram experiment was found to be similar to men's obedience. Both genders displayed high levels of obedience to the authority figure, even when instructed to administer painful electric shocks to the "learner."

In a manufacturing process, a random sample of 9 bolts has a mean length of 3 inches with a variance of .09. What is the 90 percent confidence interval for the true mean length of the bolt? Assume that X, the length of a bolt, is distributed normally.

Answers

To calculate the 90% confidence interval for the true mean length of the bolt, we need to find the margin of error and then use it to create the interval.

The margin of error is given by:

Margin of error = z* (sigma / sqrt(n))

where z* is the z-score corresponding to the desired confidence level, sigma is the standard deviation, and n is the sample size.

For a 90% confidence level, the z-score is 1.645 (using a standard normal distribution table or calculator).

The standard deviation is the square root of the variance, so sigma = sqrt(0.09) = 0.3.

Substituting these values, we get:

Margin of error = 1.645 * (0.3 / sqrt(9)) = 0.33

To create the confidence interval, we add and subtract the margin of error from the sample mean:

Confidence interval = (sample mean - margin of error, sample mean + margin of error)

Substituting the sample mean and margin of error, we get:

Confidence interval = (3 - 0.33, 3 + 0.33) = (2.67, 3.33)

Therefore, we can say with 90% confidence that the true mean length of the bolt is between 2.67 inches and 3.33 inches.

George spent 80% of his savings to buy a camera. The camera cost $580. How much did he have in savings before he bought the camera?​

Answers

Answer:

George had $725 in savings

Step-by-step explanation:

Let's assume that George had x dollars in savings before he bought the camera.

According to the problem, George spent 80% of his savings to buy the camera, which means he had 20% of his savings left after the purchase. We can write this as:

0.20x = amount of savings left after buying the camera

We also know that the camera cost $580. We can set up an equation to relate the cost of the camera to the amount of savings that George had before buying the camera:

0.80x = $580

Solving for x, we get:

x = $580 / 0.80

x = $725

Therefore, George had $725 in savings before he bought the camera.

The sampling method described in the question is known as simple random sampling, which is a common method of selecting a representative sample from a population.

In this method, each member of the population is assigned a unique number, and a certain number of individuals are selected randomly from the population.

Simple random sampling is a type of probability sampling, which means that each member of the population has an equal chance of being selected for the sample.

This is important because it ensures that the sample is representative of the population as a whole, and reduces the risk of sampling bias.

The process of simple random sampling is straightforward and easy to implement, making it a popular choice for researchers. However, it can be time-consuming and may not be practical for very large populations. In such cases, other sampling methods such as stratified sampling or cluster sampling may be more appropriate.

Mavis wants to move each counter to an adjacent square (horizontally or vertically, but not diagonally), so that as originally, each square contains exactly one counter. In how many ways can she do this

Answers

Thus, there are over 2 trillion ways for Mavis to move each counter to an adjacent square without having any of them end up in the same square.

There are several ways Mavis can move each counter to an adjacent square, but the question is how many ways can she do this without having two counters end up in the same square.

First, let's consider the top row of the board. There are 7 counters, and each counter has two adjacent squares that it can move to.

However, the counter on each end only has one adjacent square to move to. So, the total number of ways to move the counters in the top row without any of them ending up in the same square is:

2 x 2 x 2 x 2 x 2 x 2 x 1 = 64

Now, let's consider the second row. There are also 7 counters in this row, but the two end counters now have two adjacent squares to move to.

However, there is a new constraint: each counter in the second row must move to a square that is not occupied by a counter in the top row.

This means that the first and last counters in the second row each have three possible squares to move to, while the other five counters each have two possible squares to move to.

So, the total number of ways to move the counters in the second row without any of them ending up in the same square is:

3 x 2 x 2 x 2 x 2 x 2 x 3 = 288

We can continue this process for each row, taking into account the constraints of not having any counters end up in the same square and not moving to squares already occupied in the previous row.

In the end, the total number of ways Mavis can move the counters to adjacent squares is the product of the number of ways for each row:

64 x 288 x 288 x 288 x 288 x 288 x 64 = 2,051,717,760,000

Therefore 1.96 is the z critical value that is to be used here.

As we are not given a prior proportion value here, we take p = 0.5, to get a conservative value of the sample size.

The margin of error now is computed as:

MOE = x*P(1 - p)

n = 22 P(1-7 .)2 x 0.25 = 9604 MOE2

Therefore 9604 is the required minimum sample size here.

In recent years, the United States has experienced a sharp increase in obesity rates (in particular amongst teenagers), which is considered to increase the probability of chronic diseases like diabetes. Even if the dependency ratio is constant, what would be the effect of such a trend on the size of the government debt

Answers

The increase in obesity rates in the United States, particularly among teenagers, can have a significant impact on the size of the government debt, even if the dependency ratio remains constant.

Obesity is linked to an increased risk of chronic diseases such as type 2 diabetes, heart disease, and certain cancers. These chronic diseases require costly medical treatments and care, which can put a strain on the government's finances. In turn, the government may need to spend more on healthcare programs, such as Medicaid and Medicare, to cover the costs of treating these chronic diseases.

Additionally, obesity can lead to a reduction in economic productivity and an increase in disability rates, which can result in lower tax revenues and higher disability payments. This reduction in economic productivity can also have a negative impact on economic growth, further exacerbating the debt problem.

Therefore, the increase in obesity rates in the United States can lead to increased government spending on healthcare and disability programs, lower tax revenues, and slower economic growth. All of these factors can contribute to an increase in the size of the government debt.

True or false: If a relationship exists between a response variable Y and a predictor variable X it is appropriate to say that X causes variation in Y.

Answers

If a relationship exists between a response variable Y and a predictor variable X, it is appropriate to say that X causes variation in Y is True.

There could be other factors or variables that influence the relationship between X and Y. It is important to distinguish between correlation and causation.
To establish causation, a researcher needs to conduct a controlled experiment, where all other factors are held constant except for the predictor variable X.

This will allow the researcher to isolate the effect of X on Y and determine whether it is indeed causing variation in Y.
In conclusion, while a relationship between X and Y may suggest causation, it is not appropriate to make that assumption without conducting a controlled experiment or considering other factors that may be influencing the relationship.
True. If a relationship exists between a response variable Y and a predictor variable X, it is appropriate to say that X causes variation in Y.
In statistics, response variables, also known as dependent variables, are the outcomes we are interested in explaining or predicting.

Predictor variables, also called independent variables, are the factors that might influence these outcomes.

When analyzing data, we often use regression models to determine the strength and direction of the relationship between the response variable Y and the predictor variable X.
A positive relationship between X and Y means that as X increases, Y also increases, while a negative relationship implies that as X increases, Y decreases.

A strong relationship between the variables indicates that the predictor variable X accounts for a significant portion of the variation in the response variable Y.
However,

It's crucial to note that a correlation between X and Y does not guarantee causality.

Confounding variables, which are factors not included in the analysis but may influence the response variable, could be causing the observed relationship.

Further analysis,

Such as experiments or controlling for potential confounding variables, might be needed to establish causation.
In summary,

When a relationship exists between a response variable Y and a predictor variable X, it is appropriate to say that X causes variation in Y, but it's important to consider that correlation does not necessarily mean causation.

On a toll road, there are 7 lanes for drivers to pay their toll. Customer arrival times are random, with an exponential distribution. Service times are random, with an exponential distribution. What is the proper description for this queueing system.

Answers

Queueing system can be analyzed using queueing theory to determine performance measures such as the average queue length, average waiting time, and utilization of the service channels.

The queueing system you have described can be modeled as an M/M/7 queue, where:

M represents that inter-arrival times and service times are exponentially distributed.

M represents that the arrival process is memoryless, meaning that the probability of a customer arriving at any given time does not depend on the previous arrival times or the state of the system.

7 represents the number of service channels, or lanes, available for customers to pay their toll.

The notation for this system is M/M/7, which indicates that it has an infinite queue capacity and that there is no limit to the number of customers that can be waiting in the queue.

In this queueing system, customers arrive randomly and independently, and they join the queue if all lanes are busy. They are served on a first-come, first-served basis, with the service times also being exponentially distributed.

This queueing system can be analyzed using queueing theory to determine performance measures such as the average queue length, average waiting time, and utilization of the service channels.

Find f(x) if f(2) = 1 and the tangent line at x has slope (x − 1)ex2 − 2x.

f(x)= _____________

Answers

If f(2) = 1 and the tangent line at x has slope (x − 1)ex2 − 2x. f(x) = ((x^2 - 2x + 1)/2)e^(x^2 - 2x).

To find f(x), we'll first integrate the given slope function to obtain the original function. The slope of the tangent line is given as (x - 1)e^(x^2 - 2x).

Let F'(x) = (x - 1)e^(x^2 - 2x). To find f(x), we need to integrate F'(x) with respect to x:

∫(x - 1)e^(x^2 - 2x) dx

Now, we can use substitution. Let u = x^2 - 2x, then du = (2x - 2) dx. Therefore, the integral becomes:

∫((u + 1)/2)e^u du

Now, we can integrate by parts. Let v = e^u, then dv = e^u du. Let w = (u + 1)/2, then dw = 1/2 du. Using integration by parts formula:

∫w dv = wv - ∫v dw

∫(u + 1)/2 * e^u du = ((u + 1)/2)e^u - ∫(1/2)e^u du

Now integrate the remaining part:

∫(1/2)e^u du = (1/2)e^u + C

Substituting back:

f(x) = ((x^2 - 2x + 1)/2)e^(x^2 - 2x) + C

Now, use the given condition f(2) = 1:

1 = ((2^2 - 2*2 + 1)/2)e^(2^2 - 2*2) + C

1 = (1)e^0 + C

C = 0

A school system has 16 bus drivers that must cover 12 bus routes. Each driver can cover at most one route. The driver's bids for the various routes are listed in the file P05_45.xlsx. Each bid indicates the amount the driver will charge the school system to drive that route. How should the drivers be assigned to the routes to minimize the school system's cost

Answers

Since each driver can cover at most one route, we will continuous this process until all 12 routes have been assigned to a driver. This will ensure that the school system pays the least amount possible for the 12 bus routes.

To minimize the school system's cost while assigning drivers to the bus routes, follow these steps:

1. Open the file P05_45.xlsx and arrange the data in a clear format, such as a table with drivers listed vertically and routes listed horizontally. Each cell should contain the amount a driver charges for a specific route.

2. Identify the lowest bid for each route. You can do this by going through each column (representing a route) and finding the minimum amount.

3. Assign the driver with the lowest bid to the corresponding route. Make sure to keep track of which drivers have already been assigned to avoid assigning them to multiple routes.

4. Continue this process for all 12 routes. Remember, each of the 16 drivers can only be assigned to one route.

5. Once all drivers have been assigned to the routes, add up the amounts for each assigned driver to find the total cost for the school system.
