My Wife Used to Work for the Gap

Essay

My wife used to work for the Gap. Ever since she started working there, I've become very sensitive to the way people dress, and it seems to me like every adult in America between the ages of 18-40 owns about six items of gap clothing. Upon hearing this, you think "Dr. Urdan's crazy! That's way too high! I bet the average adult doesn't own nearly that many articles of Gap clothing." Suppose you wanted to test this hypothesis. You select a random sample of 20 American adults between the ages of 18-40 and find that, on average, each owns five items of Gap clothing, with a standard deviation of 1. Using an alpha level of .01, tell me what you conclude about our competing hypotheses. Wrap words around your final result.
