From the information given, (a) construct the indicated sample space and (b) answer the probability question.
a. A couple planning to have three children.
b. Find the probability of having exactly one girl.

Answers

Answer:

(a) 3 (b) 1/3

Step-by-step explanation:

The probability is defined as the ratio  of number of elements in event to the number of elements in sample space.

(a) As the total number of child is 3, so the number of elements in sample space = 3

(b) The sample space is { boy, boy, girl}

So, the probability is 1/3.

La temperatura exterior era de 8 grados a la medianoche. La temperatura bajó 5 grados durante cada una de las siguientes 3 horas. ¿Cuál era la temperatura a las 3 a.m.?​

Answers

Answer:

A las 3 AM la temperatura era de -7 grados.

Step-by-step explanation:

Dado que la temperatura exterior era de 8 grados a la medianoche, y la temperatura bajó 5 grados durante cada una de las siguientes 3 horas, para determinar cuál era la temperatura a las 3 a.m. se debe realizar el siguiente cálculo:

8 - (3 x 5) = X

8 - 15 = X

-7 = X

Por lo tanto, a las 3 AM la temperatura era de -7 grados.

Answers

Answer:

Following are the responses to the given question:

Step-by-step explanation:

Mean Absolute Deviation MAD

[tex]MAD = \sum_{i=1}^{n} \frac{\left | actual_{i}-forecast_{i} \right |}{n}[/tex]

Mean squared error  

[tex]MSE=\Sigma^{n}_{i=1} \frac{(Actual_i - Forecast_i)^2}{(n - 1)}[/tex]

linear trend equation is [tex]Ft = 124 + 2t[/tex]

[tex]MAD = \frac{23}{10} = 2.3\\\\MSE = \frac{91}{9}= 10.11\\\\[/tex]

Naive method

[tex]MAD = \frac{36}{9} = 4\\\\MSE = \frac{202}{8}=25.25\\\\MAD (Naive) = 4\\\\MAD (Linear) =2.3\\\\MSE (Naive)=25.25\\\\MSE (Linear)=10.11\\\\[/tex]

A researcher investigated whether following a vegetarian diet could help to reduce blood pressure. For a sample of 85 people who followed a vegetarian diet for 4 months, the mean systolic blood pressure was 124 mmHg. For a sample of 75 people who followed a non-vegetarian diet for 4 months, the mean systolic blood pressure was 138 mmHg. Methods of statistics show that if a vegetarian diet had no effect on blood pressure, there would be less than 1 chance in 100 of getting these results. Does the result have statistical significance? Why or why not? Does the result have practical significance?

Answers

Answer:

Yes, the result does not have statistical significance

Yes, the result has practical significance

Step-by-step explanation:

An experiment or claim may be said to be statistically significant if it's occurence is likely not due to chance for a certain level of stated significance. From the scenario described, it is stated that if vegetarian diet has no effect on blood, then the result obtained wipukd likely occur in less Than 1 of 100 ; this is < 0.01. This means that the effect of vegetarian diet on blood could not have occurred by chance. Hence, result is statistically significant.

The result does have practical significance too, since there is a distinctive difference in blood pressure of non - vegetarians(138mmHg) and Vegetarians (124mmHg).

Step-by-step explanation:

Recall: the exterior angle theorem of a triangle states that an exterior angle is equal to the sum of the two opposite interior angles of a triangle.

❌Option 1 CANNOT be true

Rationale:

m<1 is an exterior angle of triangle ∆ABC and ∆EBC, so based on the exterior angle theorem of a triangle, m<1 = m<3 + m<4 or m<1 = m<ABC + m<5

❌Option 2 CANNOT be true.

Rationale:

m<5 ≠ m<3 - m<2

❌Option 3 CANNOT be true.

A random sample of 10 subjects have weights with a standard deviation of 12.7363 kg. What is the variance of their​ weights?

Answers

Answer:

Variance, V = 162.2133 kg²

Step-by-step explanation:

Given the following data;

Standard deviation = 12.7363 kg.

To find the the variance of their weights?

Mathematically, standard deviation is equal to the square root of variance.

[tex]Sd = \sqrt{V}[/tex]

Where;

Sd is the standard deviation of the sample.

V is the variance of the sample.

Substituting into the formula, we have;

[tex]12.7363 = \sqrt{V}[/tex]

Taking the square of both sides, we have;

[tex]12.7363^{2} = V [/tex]

Variance, V = 162.2133 kg²

In psychology, aptitude tests are designed to measure the ability to learn. Questions are designed to be age appropriate so as not to be biased toward age due to knowledge acquired. In this study, an aptitude test is given on the skills necessary to use apps on a smart phone. An aptitude test with a maximum score of 150 is given to measure the ability to learn how to use apps on a smartphone.
The regression line for the predicted value of aptitude given age is as follows:
Aptitude = 111.3 - 1.13*Age
Find the expected aptitude test score for a person whose age is 15 years. Your answer should be rounded to the nearest whole number.

Answers

Answer:

The expected aptitude test score for a person whose age is 15 years is 94.

Step-by-step explanation:

Aptitude formula in function of age:

The aptitude A in function of age a is given by:

[tex]A(a) = 111.3 - 1.13a[/tex]

Find the expected aptitude test score for a person whose age is 15 years.

This is A when a = 15. Thus, finding the numeric value of the function:

[tex]A(a) = 111.3 - 1.13a[/tex]

[tex]A(15) = 111.3 - 1.13(15) = 94.35[/tex]

Rounding to the nearest whole number, 94.

In this question, we first explain the expected aptitude test after that we calculate its value.

The test of aptitude allows employers to assess the skills of a candidate via a variety of test formats. Required to test your ability to do things and react to working circumstances is tested. It includes, among others, problem-solving, prioritization as well as numeracy skills.When a score of 100% again for a perfect aptitude test, as well as a score of 80% or greater is considered a good person with the minimum acceptable score is deemed to be between 70% and 80%.

Given:

[tex]\to \bold{Aptitude = 111.3 - 1.13*Age}[/tex]

[tex]\to \bold{Age= 15 \ years}\\\\[/tex]

Putting the age value into the Aptitude equation to calculate its value:

[tex]\bold{= 111.3 - 1.13*(15)}\\\\\bold{= 111.3 - 16.95}\\\\\bold{=94.35 \approx 94} \\\\[/tex]

Therefore, For a person 15 years of age 94, the anticipated test score for aptitude.

Answers

i actually dont know this

Yes, they are quite similar. the p-value obtained using the theory-based method (p < 0.0001) agree with that obtained using the randomization/simulation - based method (p < 0.0001)

P- value is the probability of obtaining a value of test statistic more extreme in the direction of alternative hypothesis than the observed one. In easy words if p -value < level of significance we reject H0 in favor of H1.

Here:

p-value < 0.0001 => we reject H0.

If the statistical software renders a p value of 0.000 it means that the value is very low, with many "0" before any other digit.

So the interpretation would be that the results are significant, same as in the case of other values below the selected threshold for significance.

Therefore, yes they are quite similar.

Answers

Answer:

0.6 probability that [tex]-2 \leq x \leq 2[/tex]

Step-by-step explanation:

The probability distribution is given in the table.

Probability that x is between -2 and 2.

Between -2 and 2, inclusive, we have -2, 0 and 2. So

[tex]P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2)[/tex]

From the table:

[tex]P(X = -2) = 0.33, P(X = 0) = 0.16, P(X = 2) = 0.11[/tex]. So

[tex]P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2) = 0.33 + 0.16 + 0.11 = 0.60[/tex]
