# The Fast N’ Hot food chain wants to test if their “Buy One, Get One Free”...

The Fast N’ Hot food chain wants to test if their “Buy One, Get One Free” program increases customer traffic enough to support the coast of the program. For each of 15 stores, one day 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. At x=0.05, test the hypothesis that the mean difference is at most 0 (at best the program makes no difference, or worse it decreases traffic) against the alternative that the mean difference > 0 (the program increase traffic).

 Customer Traffic With Program Without Program 149 140 225 233 112 110 52 42 336 332 146 135 143 151 35 33 185 178 147 147 167 162 249 243 161 149 44 48 347 346

The pvalue of 0.084 provides weak evidence against H0. H0 is not rejected at x=0.05. You decide the evidence is not strong enough to recommend further evaluation of the program.

The pvalue rejects H0: Mean difference >0.

The pvalue of 0.033 provides strong evidence against H0. H0 is rejected at x=0.05. You decide to recommend further evaluation of the program.

None of the answers are correct.

The pvalue of 0.221 indicates that the data provide insignificant evidence against H0. H0 is not rejected at x=0.05. You decide to conclude the study and not to recommend the program.

The pvalue of 0.002 provides overwhelming evidence against H0. H0 is rejected at x=0.05. You decide that the program results in increased customer traffic, overall, and recommend the program be implemented.

The pvalue of 0.033 provides strong evidence against H0. H0 is rejected at x=0.05. You decide to recommend further evaluation of the program.
