The movie complex at a shopping mall shows three movies simultaneously on the same evening. On a recent Friday evening, each movie drew a capacity crowd. A sample of the evening’s movie patrons have been coded according to whether they purchased snacks (1 = pur chased snacks, 2 = did not purchase snacks) and which movie they attended (1 = the “G” movie, 2 = the “PG” movie, and 3 = the “R” movie). The data are in file XR13049. At the 0.025 level, could the percentage buying snacks be the same for all three movies?
