Suppose you conduct a hypothesis test about a population mean when the standard deviation is known (a “z test”) by calculating a z statistic and determining whether to reject the null hypothesis. Assume that your z statistic is a positive value and that you will reject the null hypothesis when z is very large. Listed below are possible changes to the study design or to the results of the study. Determine whether the likelihood of rejecting the null hypothesis increases, decreases, or stays the same for each of these changes.
