Chapter 10: Q. 84 (page 687)

Explain why it is not appropriate to perform a paired ttest about the true mean difference (Male 鈭� Female) in literacy rates in Islamic countries.

Short Answer

Expert verified

All the conditions are not satisfied since the random condition and large sample is not satisfied and it is therefore not appropriate to determine the confidence interval for the population mean difference.

Step by step solution

01

Step 1. To find

Here we have to find why it is not appropriate to perform a paired t test about the true mean difference (Male 鈭� Female) in literacy rates in Islamic countries.

02

Step 2. Explanation

To answer the question we must find out if the three conditions are satisfied or not, which is as:

Random: It is not satisfied because the samples included largely Muslim nations and thus the small nations were ignored which implies no random sample.

Independent: It is satisfied because the sample of Muslim nations is less than of all population of Muslim nations.

Normal: It is not satisfied because the sample is not large and the distribution is not approximately Normal.

Thus, all the conditions are not satisfied since the random condition and large sample is not satisfied and it is therefore not appropriate to determine the confidence interval for the population mean difference.

Final grades for a class are approximately Normally distributed with a mean of 76and a standard deviation of 8. A professor says that the top10%of the class will receive an A, the next20%a B, the next 40%a C, the next 20%a D, and the bottom 10%an F. What is the approximate maximum grade a student could attain and still receive an F for the course?

Bag lunch? Phoebe has a hunch that older students at her very large high

school are more likely to bring a bag lunch than younger students because they have grown tired of cafeteria food. She takes a simple random sample of 80 sophomores and finds that 52of them bring a bag lunch. A simple random sample of 104seniors reveals that 78of them bring a bag lunch.

a. Do these data give convincing evidence to support Phoebe鈥檚 hunch at the 伪=0.05significance level?

b. Interpret the P-value from part (a) in the context of this study.

Steroids in high school A study by the National Athletic Trainers Association surveyed random samples of 1679high school freshmen and 1366 high school seniors in Illinois. Results showed that 34of the freshmen and 24of the seniors had used anabolic steroids. Steroids, which are dangerous, are sometimes used in an attempt to improve athletic performance. Researchers want to know if there is a difference in the proportion of all Illinois high school freshmen and seniors who have used anabolic steroids.

a. State appropriate hypotheses for performing a significance test. Be sure to define the parameters of interest.

b. Check if the conditions for performing the test are met.

Young adults living at home A surprising number of young adults (ages 19

to 25) still live in their parents鈥� homes. The National Institutes of Health surveyed

independent random samples of 2253men and 2629women in this age group. The survey found that 986 of the men and 923 of the women lived with their parents.

a. Construct and interpret a 99%confidence interval for the difference in the true

proportions of men and women aged 19-25who live in their parents鈥� homes.

b. Does your interval from part (a) give convincing evidence of a difference between the population proportions? Justify your answer.

Steroids in high school Refer to Exercise 16.

a. Explain why the sample results give some evidence for the alternative hypothesis.

b. Calculate the standardized test statistic and P-value.

c. What conclusion would you make?
