In one Pepsi commercial, an announcer states that "in a recent blind taste test, more than half of the surveyed preferred diet Pepsi over diet coke." Suppose that out of 100, 56 preferred Diet Pepsi. Test the hypothesis using alpha = 0.05 that more than half of all participants will select diet Pepsi in a blind taste test. Find the test statistic:
