emily is making a histogram for the data 12 24 56 7 34 75 34 86 34 78 and 96, which is the most appropriate first interval?

A. 0-5

B. 0-10

C. 0-50

D. 0-100

Answers

Answer 1

Answer:

Option B. is correct

Step-by-step explanation:

Given:

Data: 12 24 56 7 34 75 34 86 34 78 and 96

To find: the most appropriate first interval

Solution:

A histogram is a pictorial representation to display frequency data using rectangular bars.

In histogram, each bar is for a range of data.

For the given data, options A. is not appropriate as the least value given in the data is 7.

Option C. is not appropriate as then the data falls under just two intervals only.

Option D. is not appropriate as then the data falls under just one interval only.

Option B. is the most appropriate first interval

A new screening test for Lyme disease is developed for use in the general population. The sensitivity and specificity of the new test are 60% and 70%, respectively. Three hundred people are screened at a clinic during the first year the new test is implemented. Assume the true prevalence of Lyme disease among clinic attendees is 10%.

Calculate the following values:

The predictive value of a positive test

The predictive value of a negative test

Answers

Answer:

predictive value of a positive test = 18.18%

predictive value of a negative test = 94.03%

Step-by-step explanation:

Sensitivity = 60% = 0.6

Specificity = 70% = 0.7

Let True Positive = TP

True Negative = TN

False Negative = FN

[tex]Sensitivity = \frac{TP}{TP + FN} \\0.6 = \frac{TP}{TP + FN} \\0.6TP + 0.6FN = TP\\0.4TP = 0.6FN\\TP = 1.5 FN[/tex]

[tex]Specificity = \frac{TN}{TN + FP} \\0.7 = \frac{TN}{TN + FP} \\0.7TN + 0.7FP = TN\\0.7FP = 0.3 TN\\TN = 7/3 FP[/tex]

Prevalence = 10% = 0.1

Three hundred people are screened, [tex]T_{total} = 300[/tex]

Total number of people having the disease, [tex]T_{disease} = ?[/tex]

[tex]Prevalence = \frac{T_{disease} }{T_{total} } \\0.1 = \frac{T_{disease} }{300 }\\T_{disease} = 30[/tex]

[tex]T_{disease} = TP + FN\\30 = TP + FN[/tex]

But TP = 1.5 FN

30 = 1.5 FN + FN

30 = 2.5 FN

FN = 30/2.5

FN = 12

TP = 1.5 FN = 1.5 * 12

TP = 18

[tex]FP + TN = T_{total} - T_{disease} \\FP + TN = 300 - 30\\FP + TN = 270\\FP + \frac{7}{3} FP = 270\\\frac{10}{3} FP = 270\\FP = 27 * 3\\FP = 81[/tex]

81 + TN = 270

TN = 189

To calculate the Predictive value of positive test (PPT)

[tex]PPT = \frac{TP}{TP + FP} * 100\\PPT = \frac{18}{18+81} * 100\\PPT = \frac{18}{99} * 100\\PPT = 18.18 \%[/tex]

To calculate the Predictive value of negative test (PNT)

[tex]PPT = \frac{TN}{FN + TN} * 100\\PPT = \frac{189}{189+12} * 100\\PPT = \frac{189}{201} * 100\\PPT = 94.03 \%[/tex]

The Community College Survey of Student Engagement reports that 46% of the students surveyed rarely or never use peer or other tutoring resources. Suppose that in reality 40% of community college students never use tutoring services available at their college. In a simulation, we select random samples from a population in which 40% do not use tutoring. For each sample, we calculate the proportion who do not use tutoring. If we randomly sample 100 students from this population, the standard error is approximately 5%. Would it be unusual to see 46% who do not use tutoring in a random sample of 100 students?a) Yes, this would be unusual because 46% is more than one standard error from the mean. It is very rare for a sample to be more than one standard error from mean. b) Yes, this would be unusual because 46% is 6% higher than 40%. c) No, this would not be unusual because the error is only 6%. d) No, this would not be unusual because 46% is only 1.2 standard errors from 40%.

Answers

Answer:

d) No, this would not be unusual because 46% is only 1.2 standard errors from 40%.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

If the z-score is higher than 2 or lower than -2, X is unusual.

In this question:

Mean = 40%. So [tex]\mu = 0.4[/tex]

Standard error = 5%. So [tex]\sigma = 0.05[/tex]

Is 46% unusual?

We have to find Z when X = 0.46. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{0.46 - 0.4}{0.05}[/tex]

[tex]Z = 1.2[/tex]

1.2 is lower than 2, that is, it is only 1.2 standard deviations from the mean.  So 46% is not unusual.

So the correct answer is:

d) No, this would not be unusual because 46% is only 1.2 standard errors from 40%.

if 9 more than twice a number is 3 less than three times the same number, what is the number?

Answer:

the number is 12

Step-by-step explanation:

9+2x=3x-3

12=x

The required number is 12.

What are linear equation?

A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.

Now it is given that,9 more than twice a number is 3 less than three times the same number.

Let the number be x.

So, 9 more than twice a number = 9 +2x

and, 3 less than three times the same number = 3x - 3

Hence we have,

9 + 2x = 3x - 3

Adding 3 both the side we get,

12 + 2x = 3x

Now substracting 2x both the side we get,

x = 12

Hence the number is 12.

The National Transportation Safety Board publishes statistics on the number of automobile crashes that people in various age groups have. A researcher claims the population proportion of young drivers, ages 18 – 24, having accidents is greater than 12%. Her study examined 1000 young drivers ages 18 – 24 and found that 134 had an accident this year. Test at α = .05. a) State H0 and Ha b) Find the critical value, show work c) Find the appropriate test statistic, show work d) Do a P - value test e) Make a decision to reject or fail to reject the null hypothesis and interpret the results.

Answers

Answer:

a) Null hypothesis:[tex]p\leq 0.12[/tex]  

Alternative hypothesis:[tex]p > 0.12[/tex]  

b) [tex] z_{\alpha}=1.64[/tex]

c) [tex]z=\frac{0.134 -0.12}{\sqrt{\frac{0.12(1-0.12)}{1000}}}=1.362[/tex]  

d) [tex]p_v =P(z>1.362)=0.0866[/tex]  

e) For this case since the statistic is lower than the critical value and the p value higher than the significance level we have enough evidence to FAIL to reject the null hypothesis so then we don't have information to conclude that the true proportion is higher than 0.12

Step-by-step explanation:

Information given

n=1000 represent the random sample selected

X=134 represent the number of young drivers ages 18 – 24 that had an accident

[tex]\hat p=\frac{134}{1000}=0.134[/tex] estimated proportion of young drivers ages 18 – 24 that had an accident

[tex]p_o=0.12[/tex] is the value that we want to verify

[tex]\alpha=0.05[/tex] represent the significance level

Confidence=95% or 0.95

z would represent the statistic

[tex]p_v{/tex} represent the p value

Part a

We want to verify if the population proportion of young drivers, ages 18 – 24, having accidents is greater than 12%:  

Null hypothesis:[tex]p\leq 0.12[/tex]  

Alternative hypothesis:[tex]p > 0.12[/tex]  

The statistic would be given by:

[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)  

Part b

For this case since we are conducting a right tailed test we need to find a critical value in the normal standard distribution who accumulates 0.05 of the area in the right and we got:

[tex] z_{\alpha}=1.64[/tex]

Part c

For this case the statistic would be given by:

[tex]z=\frac{0.134 -0.12}{\sqrt{\frac{0.12(1-0.12)}{1000}}}=1.362[/tex]  

Part d

The p value can be calculated with the following probability:

[tex]p_v =P(z>1.362)=0.0866[/tex]  

Part e

For this case since the statistic is lower than the critical value and the p value higher than the significance level we have enough evidence to FAIL to reject the null hypothesis so then we don't have information to conclude that the true proportion is higher than 0.12
