Moving Out In Exercises 17–20, use the figure below, which shows the percentages of 18- to 24-year-olds in the United States who live in their parents’ homes for males and females in 2000 and 2012. Assume the survey included random samples of 250 men and 280 women in 2000 and 260 men and 270 women in 2012.
17. Men: Then and Now At a = 0.05, can you support the claim that the proportion of men ages 18 to 24 living in their parents’ homes was greater in 2012 than in 2000?
18. Women: Then and Now At a = 0.05, can you support the claim that the proportion of women ages 18 to 24 living in their parents’ homes was greater in 2012 than in 2000?
19. Then: Men and Women At a = 0.01, can you reject the claim that the proportion of 18- to 24-year-olds living in their parents’ homes in 2000 was the same for men and women?
20. Now: Men and Women At a = 0.10, can you reject the claim that the proportion of 18- to 24-year-olds living in their parents’ homes in 2012 was the same for men and women?
