We want to conduct a hypothesis test of the claim that the population mean daily profit of a convenience store is less than 480 dollars. So, we record the daily profit for a random sample of days. The sample has a mean of 495 dollars and a standard deviation of 74 dollars. 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 12, and it is from a population with a distribution about which we know very little. O²=E Z 01- OIt is unclear which test statistic to use. X Ś (b) The sample has size 80, and it is from a non-normally distributed population with a known standard deviation of 76. 02= 01-0 It is unclear which test statistic to use.
