For each of 15 stores, one davr is selected at random to record customer traffic with the program in effect, and one day is selected at random to record customer traffic with program not in effect. The results of the experiment are documented in DATA. For each store, compute difference = traffic with program minus traffic without program. At at = [1.05, test the hvpothesis that the mean difference is at most ID {at best the program makes no difference, or worse it decreases traffic] against the alternative that the mean difference a D [the program increases traffic}. 0 The pvalue rejects HID: Mean difference a D. O The pvalue of CLUBS provides strong evidence against HD. HD is rejected at o: = {1.05. You decide to recommend further evaluation of the program. 0 The pvalue of [1221 indicates that the data provide insignificant evidence against Hi). HD is not rejected at o: = 0.05. You decide to conclude the studv and not to recommend the program. 0 The pvalue of DDEM provides weak evidence against H0. H0 is not rejected at Di = {105. You decide the evidence is not strong enough to recommend further evaluation of the program. 0 The pvalue of EDGE provides overwhelming evidence against HUI. H0 is rejected at Dr. = DDS. You decide that the program results in increased customer traffic, overall, and recommend the program be implemented. 0 None of the answers are correct
