For the following study, indicate your conclusion and the rejection area(s). Z Score Cutoff +1.64 Z Score Obtained -1.76 A. Reject the null, areas A and C B. Reject the null, area B C. Reject the null, area C D. Reject the null, area A E. Fail to reject the null, area C ChatGPT The rejection area for a one-tailed test with a significance level of 0.05 corresponds to the extreme upper 5% of the distribution, which is to the right of the z-score of approximately +1.645 (area A in a standard normal distribution). Since the obtained z-score is +1.76, which falls into the rejection area, we would reject the null hypothesis. Therefore, the correct answer is: D. Reject the null, area A User For the following study, indicate your conclusion and the rejection area(s). Z Score Cutoff Z Score Obtained +1.64 +1.76 A. Reject the null, areas A and C B.
