In a study conducted to investigate browsing activity by shoppers, each shopper was initially classified as a nonbrowser, light browser, or heavy browser. For each shopper, the study obtained a measure to determine how comfortable the shopper was in a store. Higher scores indicated greater comfort. Suppose the following data were collected. Light Нeavy Nonbrowser Browser Browser 10 4 10 6. 11 12 4 11 10 10 4 11 10 a. Use a = .05 to test for a difference among mean comfort scores for the three types of browsers.
