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 meas to determine how comfortable the shopper was in a store. Higher scores indicated greater comfort. Suppose the following data were collected. Light Browser Heavy Browser Nonbrowser 4 5 6. 7 4 4 7 7 4 4 6 5 5 5 4 7 (a) Use a = 0.05 to test for differences among comfort levels for the three types of browsers. State the null and alternative hypotheses. Ho: HNB * HLB * HHB H: HNB = HLB = HHB O Ho: HNB = HLB = HHB H: HNB * HLB * HHB O Ho: HNB = HLB = HHB H: Not all the population means are equal. O Ho: At least two of the population means are equal. H: At least two of the population means are different. O Ho: Not all the population means are equal. H: HNB = HLB - HHB Find the value of the test statistic. (Round your answer to two decimal places.)
