Young adults living at home A surprising number of young adults (ages 19 to 25 ) still live in their parents' homes. A random sample by the National Institutes of Health included 2253 men and 2629 women in this age group. ${ }^{11}$ 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 to 25 who live in their parents' homes. (b) Does your interval from part (a) give convincing evidence of a difference between the population proportions? Explain.

A surprising number of young adults (ages 19 to 25) still live in their parents’ homes. The National Institutes of Health surveyed independent random samples of 2153 men and 2729 women in this age group. The survey found that 986 of the men and 923 of the women lived with their parents. Construct and interpret a 99% confidence interval for the difference in the true proportions of men and women aged 19 to 25 who live in their parents’ homes. Does this give convincing evidence of a difference between the population proportions? Explain.

A number of young adults, ages 19 to 25, live with their parents. Data were collected, and the proportion of men and women in that age group who live with their parents was calculated. A 90% confidence interval for pM - pW was found to be (0.064, 0.110). (a) What is the value of the sample statistic that you would use to estimate the difference in the population proportions for men and women living with their parents to be? (Use a positive #)

A surprising number of young adults (ages 19 to 25) still live in their parents' home. A random sample by the National Institutes of Health included 2253 men and 2629 women in this age group. The survey found that 986 of the men and 923 of the women lived with their parents. Is this good evidence that different proportions of young men and young women live with their parents? How large is the difference between the proportions of young men and young women who live with their parents? Construct a 99% confidence interval for p1, the difference between the proportions of young men and young women who live with their parents. You do not need to verify conditions. Show all work.
