The Fast N' Hot food chain wants to test if the "Buy One, Get One Free" program increases customer traffic enough to support the cost 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 wit the 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 Alpha of .05, test the hypothesis that the mean difference is at most 0 ( at best the program makes no difference, or worse it decrease traffic) against the alternative that the mean difference > 0 (the program traffic increase)
