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 3.1 penalties per game. So, we choose a random sample of games. The sample has a mean of 3 penalties per game and a standard deviation of 0.6 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 16, and it is from a normally distributed population with an unknown standard deviation. O It is unclear which test statistic to use. ? (b) The sample has size 14, and it is from a normally distributed population with a known standard deviation of 0.59. O z=0 O It is unclear which test statistic to use.
