Textbook Question
Chapter 8.4, Problem 22E
U.S. Workforce In Exercises 19–22, use the figure shown at the left, which gives the percentages of full-time employed men and women in the United States who work 40 hours per week and who work more than 40 hours per week. Assume the survey included random samples of 300 men and 250 women. (Adapted from Gallup)
22. Working More Than 40 Hours Per Week: Men and Women At α = 0.10, can you support the claim that the proportion of the U.S. workforce that works more than 40 hours per week is less for women than for men?

How is my work? Should anything be changed?
A researcher wanted to examine the effect of a new math study skills program on second graders. Fifteen students took the new study skills program for six weeks and then took a standardized math exam, which is known to have a population mean score of µ = 80. The scores on the exam for the 15 students (who took the study skills program) are reported below.
Scores on the standardized math exam for the 15 students:78, 85, 83, 75, 81, 85, 84, 82, 78, 83, 78, 90, 85, 83, 81
Test to see whether the students who took the new study skills program have significantly higher test scores than the national average. Perform the appropriate test in SPSS using α = .05
a. State the null and alternative hypotheses below.
Null hypothesis:
H0: μ = 80.
Alternative hypothesis:
H1: μ > 80
b. What type of test should be run on the data (be specific with the exact name of the test)? For example, don’t just state “t test,” but the specific t-test used.

McDermott et al. titled “Sex Differences in Peripheral Arterial Disease: Leg Symptoms and Physical Functioning” (Journal of the American Geriatrics Society, Vol. 51, No. 2, pp. 222–228), the researchers obtained the ABI of 187 women with peripheral arterial disease.
