According to a recent marketing campaign, 100 drinkers of either Diet coke or Diet Pepsi participated in a blind test to see which of the drinks was their favorite. 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:

How do I find the test statistic? I don't think this number is correct. Thank you.
