Based on the information give for each of the following studies, decide whether to reject the null hypothesis, for each, give the Z- score cutoff (or cutoffs) on the comparison distribution at which the null hypothesis should be rejected, the Z score on the comparison distribution for the sample score, and your conclusion. Assume that all populations are normally distributed.
