want to conduct a hypothesis test of the claim that the population mean daily profit of a convenience store is more than 441 dollars. So, we record the a fit for a random sample of days. The sample has a mean of 454 dollars and a standard deviation of 80 dollars. reach of the following sampling scenarios, choose an appropriate test statistic for our hypothesis test on the population mean. Then calculate that statistic ound your answers to two decimal places. (a) The sample has size 15, and it is from a normally distributed population with an unknown standard deviation. O²= -0 O It is unclear which test statistic to use. Ot= (b) The sample has size 10, and it is from a normally distributed population with a known standard deviation of 78. OZ= -0 Ot= OIt is unclear which test statistic to use. X
