For given problem, give a 99% confidence interval for the difference between the proportions for viewers of the two shows who watched 1 to 6 commercials. Interpret the results.
Problem
According to a study reported in the New York Times, 48% of the viewers who watched NFL Football on TiVo viewed 1 to 6 commercials, while 26% of the viewers who watched Survivor: Cook Islands on TiVo viewed 1 to 6 commercials.
If this information is based on two independent random samples of 200 viewers each, test for equality of proportions using α = 0.05.
