According to a 2011 survey of college freshmen by UCLA's Cooperative Institutional Research Program, 39.5% of freshmen said that they had spent 6 or more hours a week studying or doing homework as high school seniors (USA TODAY, January 26, 2012). This percentage was 37.3% in the 2010 survey of freshmen by the same institution. The sample sizes for these surveys are usually very large, but for this example suppose the samples included 2000 freshmen in 2010 and 2200 freshmen in 2011. Test whether the proportions of 2010 and 2011 freshmen who spent 6 or more hours a week studying or doing homework as high school seniors are different. Use a 1% significance level.
