Xr13-110* The market for breakfast cereals has been divided into several segments related to health. One company identified a segment as health-conscious adults. The marketing manager would like to know whether this segment is more likely to purchase its Special X cereal, which is pitched toward the health-conscious segment. A survey of adults was undertaken.

On the basis of several probing questions, each was classified as either a member of the health-conscious group (code  1) or not (code  2). Each respondent was also asked whether he or she buys Special X (1  no, 2  yes). The data were recorded in stacked format. Can we infer from these data that health-conscious adults are more likely to buy Special X?
