Customer Trafc W The Fast N' Hot food chain wants to test if their "Buv One. Get One Free" program 134 140 246 233 115 110 42 42 335 332 145 135 154 151 31 33 103 1?3 149 14? 1?5 152 25? 243 155 149 51 48 343 345 increases. customer traffic enough to support the cost of the program. For each of 15 stores. one dav is selected at random to record customer traffic with the program in effect. and one clav 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 o: = 0.05. test the hvpothesis that the mean difference is at most 0 [at best the program makes no difference. or worse it deueases traffic] against the alternative that the mean difference 2- 0 {the program increases traffic}. C. The pvalue of 0.221 indicates that the data provide insignificant evidence against H0. H0 is not rejected at or = 0.05. You decide to conclude the studvr and not to recommend the program. rs The pvalue of 0.084 provides weak evidence against H0. H0 is not rejected at or 2 = 0.05. You decide the evidence is not strong enough to recommend further evaluation of the program. G. The pvalue rejects H0: Mean difference 2* 0. In The pvalue of 0.002 provides overwhelming evidence against H0. H0 is rejected \\_.2' at or = 0.05. You decide that the program results in increased customer traffic. overall. and recommend the program be implemented. r: 1') None of the answers are correct. C The pvalue of 0.033 provides strong evidence against H0. H0 is rejected at or = 0.05. You decide to recommend further evaluation of the programStep by Step Solution
