Hypothesis testing

Disney tells you that the average distance between the ears on a Mickey Mouse hat is 5 inches. In a sample of 100 Mickey Mouse hats you find that the average distance between the ears on the hats is 5.2 inches with a standard deviation of 1 inch. Conduct a hypothesis test to determine if the average distance between the ears on a Mickey Mouse hat is greater than 5 inches. Assume that α = .01 and remember to clearly state the null and alternate hypothesis as well as your conclusion about the average distance between the ears of a Mickey Mouse hat.
