#20. we want to conduct a hypothesis test of the claim that the population mean daily profit of a convenient store is more than 499 dollars . so we record the daily profit for a random sample of days . the sample has a mean of $506 and a standard deviation of $75. For each of the following sampling scenarios, choose an appropriate test statistics for our hypothesis test on the population mean. Then calculate the statistic. Round your answers to two decimal places. (a) the sample has size 75, and it is from a non-normally distributed population with a known standard deviation of 75. - z= - t= - It is unclear which test statistics to use. (b) the sample has size 17, and it is normally distributed p
