Four hundred people were selected from each of the four geographic regions (Midwest, Northeast, South, West) of the United States, and they were asked which form of camping they prefer. The choices were pop-up camper/trailer, family style (tenting with sanitary facilities), rustic (tenting, no sanitary facilities), or none. The results of the survey are shown in the following table.
Based on the evidence from these samples, can you conclude that the distributions of favorite forms of camping are different for at least two of the regions? Use α = .01.
