Xr12-126* In Exercise 12.126, marketing managers for the JC Penney department store chain segmented the market for women’s apparel on the basis of personal and family values. The segments are labeled Conservative, Traditional, and Contemporary.

Recall that the classification was done on the basis of questionnaires. In addition to identifying the segment via the questionnaire, each woman was also asked to report family income (in $1,000s). Do these data allow us to infer that family incomes differ between the three market segments?
