- The box of a board game states that the average game length is 60 minutes. We play 4 games and the length of the games turns out to be 42, 54, 60, 48 minutes each. Based on this sample, test the hypothesis that the average game length is 60 minutes versus the hypothesis that the average game length is not equal to 60 minutes on a 95% confidence level. State the type of test used, write out Ho and H explicitly, then execute the test
