So, we choose a tandom sample of exam scores, The sample has a mean of 514 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.olaces (a) The sample has size 10, and it is from a normally distributed population with an unknown standard deviation. O:-0 or-0 OIRS undlear which test statistic to use. (b) The sample has size 16, and it is from a normally distributed population with a known standard deviation of 77.
