Pass the Lotion, a long-running television commercial for Special K cereal, features a flabby sunbather who asks his wife to smear sun lotion on his back. A random sample of Special K customers and a random sample of people who do not buy Special K were asked to indicate whether they liked (code = 1) or disliked (code = 2) the ad. Can we infer that Special K buyers like the ad more than non-buyers?
