We want to conduct a hypothesis test of the claim that the population mean number of holding penalties during a college football game is less than 2.4penalties per game. So, we choose a random sample of games. The sample has a mean of 2.5penalties per game and a standard deviation of 0.8 penalties per game. For each of the following sampling scenarios, choose an appropriate test statistic for our hypothesis test on the population mean. Then calculate that statistic. Round your answers to two decimal places. (a) The sample has size 100and it is from a non-normally distributed population with a known standard deviation of 0.69. O Z O T O It is unclear which test statistic to use. (b) The sample has size 18, and it is from a population with a distribution about which we know very little. O Z = O t = O It is unclear which test statistic to use
