The sample has a mean of 503 and a standard deviation of 76.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 population with a distribution about which we know very little.z=t = -0.74It is unclear which test statistic to use.(b) The sample has size 75, and it is from a non-normally distributed population with a known standard deviation of 75.z=t = 1.62It is unclear which test statistic to use.
