Chapter 11.3, Problem 51E
The Bureau of Labor Statistics (bls.gov/opub/ted/2014/ted_20141112.htm, retrieved December 13, 2016) reported that 3.8% of college graduates were unemployed in October 2013 and 3.1% of college graduates were unemployed in October 2014. Suppose that the reported percentages were based on independently selected representative samples of 500 college graduates in each of these two years. Construct and interpret a 95% confidence interval for the difference in the proportion of college graduates who were unemployed in these two years.

According to some car loan statistics, 44% of Americans are relying on an auto loan to pay for their cars. Assuming this finding to be based on a simple random sample of 1500 Americans, construct and interpret the 95% confidence interval for the population proportion of Americans who have a car loan.
From July 5-7, 2017, the Gallup Organization asked a random sample of 1,021 adults aged 18 and older living in the United States and Washington D.C. In general, how harmful do you feel secondhand smoke is to adults? and found that 59% believe that secondhand smoke is very harmful. The margin of sampling error was ±4 percentage points at the 95% confidence level.Calculate a 95% confidence interval for the percentage of all adults - aged 18 and older living in the United States and Washington D.C.- who believe that second smoke is very harmful. % to %
A doctor claims that the mean number of hours of sleep that seniors in high school get per night differs from the mean number of hours of sleep college seniors get per night. To investigate, he selects a random sample of 50 high school seniors from all high schools in his county. He also selects a random sample of 50 seniors from the colleges in his county. He constructs a 95% confidence interval for the true mean difference in the number of hours of sleep for seniors in high school and seniors in college. The resulting interval is (0.57, 1.25). Based upon the interval, can the doctor conclude that mean number of hours of sleep that seniors in high school get per night differs from the mean number of hours of sleep college seniors get per night?
