“Smartest People Often Dumbest About Sunburns” is the headline of an article that appeared in the San Luis Obispo Tribune (July 19, 2006). The article states that “those with a college degree reported a higher incidence of sunburn that those without a high school degree—43% versus 25%.” For purposes of this exercise, suppose that these percentages were based on random samples of size 200 from each of the two groups of interest (college graduates and those without a high school degree). Is there convincing evidence that the proportion experiencing a sunburn is higher for college graduates than it is for those without a high school degree? Answer based on a test with a .05 significance level.
