A poll of 974 U.S. adults split the sample into four age groups: ages 18-29, 30-49, 50-64, and 65+. In the youngest age group, 63% said that they thought the U.S. was ready for a woman president, as opposed to 34% who said "no, the country was not ready" (3% were undecided). The sample included 244 18- to 29-year olds. a) Do you expect the 99% 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 99% confidence interval for the true proportion of all U.S. adults? b) Construct a 99% confidence interval for the true proportion of all 18-to 29-year olds who believe the U.S. is ready for a woman president. a) The 99% confidence interval for the true proportion of 18- to 29-year olds who think the U.S. is ready for a woman president will be about b) The 99% confidence interval is (%). (Round to one decimal place s needed.) twice as wide as the 99% confidence interval for the true proportion of all U.S. adults who think this.
