8) (9pts) Suppose a 95% confidence level hypothesis test will be carried out to test Ho: H = 20 VS. Ho: H >20 To do this a sample of size 81 will be collected from a population with o = 16. Determine each of the following: (a) Assuming that the actual population mean is 20, compute the probability that the applicable rejection region will hold once the sample is collected. X-20 (b) Assuming that the actual population mean is 20, compute P >2.2 (c) Assuming that the actual population mean is 20, compute the probability that we will not end up rejecting the null hypothesis
