Based on the information given for each of the accompanying studies, decide whether to reject the null hypothesis. For each, give (a) the Z score cutoff (or cutoffs) on the comparison distribution at which the null hypothesis should be rejected, (b) the Z score on the comparison distribution for the sample score, and (c) the conclusion. Assume that all populations are normally distributed. EffClick the icon to view the information about each study. Click here to view page 1 of the normal curve areas table.
