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 were collected. Light Heavy Nonbrowser Browser Browser 10 9 11 10 7 12 5 8 7 9 11 10 8 6 11 10 5 10 9 a. Use a .05 to test for a difference among mean comfort scores for the three types of browsers. Compute the values identified below (to 2 decimals, if necessary).
