Fewer young people are driving. In 1983, 87% of 19-year-olds had a driver’s license. Twenty-five years later that percentage had dropped to 75% (University of Michigan Transportation Research Institute website, April 7, 2012). Suppose these results are based on a random sample of 1200 19-year-olds in 1983 and again in 2008.a. At 95% confidence, what is the margin of error and the interval estimate of the number of 19-year-old drivers in 1983?b. At 95% confidence, what is the margin of error and the interval estimate of the number of 19-year-old drivers in 2008?c. Is the margin of error the same in parts (a) and (b)? Why or why not?
