we want to conduct a hypothesis test of the claim that the population mean germination time of strawberry seeds is different from 16.9 days. So, we choose a random sample of strawberries. The sample has a mean of 17 days and a standard deviation of 1.1 days. For each of the following sampling scenarios, choose an appropriate test statistic for our hypothesis test on the population mean. Then calculate that statistic. a) the sample has size 13, and it is from a normally distributed population with a known standard deviation of 1.2 b) the sample has size 11, and it is from a population with a distribution about which we know very little.
