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 comfor Suppose the following data were collected. Light Browser Heavy Browser Nonbrowser 6. 6 3 4 3 4 4 (a) Use a- 0.05 to test for differences among comfort levels for the three types of browsers. State the null and alternative hypotheses.
