Based on the information given for each of the following 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) your conclusion. Assume that all populations are normally distributed.1. Study A, population mean = 10; population standard dev = 2; Sample score = 14; p < .05; one-tail test with high predicted.2. Study B, population mean = 10; population standard dev = 2; Sample score = 14; p < .05; two-tail test.3. Study C, population mean = 10; population standard dev = 2; Sample score = 14; p < .01; one-tail test with high predicted.4. Study D, population mean = 10; population standard dev = 2; Sample score = 14; p < .01; two-tail.5. Study E, population mean = 10; population standard dev = 2; Sample score = 14; p < .05; one-tail test with high predicted.
