Question: Perform hypothesis tests for the following:
You love donuts. You love them so that you decide to perform a study on the average diameter of donuts. You found that the average round donut size in the entire city of Los Angeles is no more than 3.2 inches. 3.2 inches is the optimum size for creating donuts per Krispy Kreme. Granny's Donuts, on the other hand, decided to measure all their donuts on a given day and found that their average donut size is 4 inches. Is the optimum donut diameter 3.2?
