A poll of U.S. adults split the sample into four age groups: ages 18-29, 30-49, 50-64, and 65+. In the youngest age group, % said that they thought the U.S. was ready for a woman president, as opposed to % who said "no, the country was not ready" (3% were undecided). The sample included 18- to 29-year-olds. a) Do you expect the % confidence interval for the true proportion of all 18- to 29-year-olds who think the U.S. is ready for a woman president to be wider or narrower than the % confidence interval for the true proportion of all U.S. adults? b) Construct a % confidence interval for the true proportion of all 18- to 29-year-olds who believe the U.S. is ready for a woman president.
