State your conclusion. 0 Reject \"0' There is not sufficient evidence to conclude that the mean comfort scores are not all the same for the three groups. C) Reject \"0' There is sufcient evidence to conclude that the mean comfort scores are not all the same for the three groups. 0 Do not reject H0. There is sufcient evidence to conclude that the mean comfort scores are not all the same for the three groups. 0 Do not reject HU' There is not sufcient evidence to conclude that the mean comfort scores are not all the same for the three groups. Use Fisher's LSD procedure to compare the comfort levels of nonbrowsers and light browsers. Use a: = 0.05. Find the value of ISD. (Round your answer to two decimal places.) .50-: Find the absolute difference between sample means for the comfort levels of nonbrowsers and light browsers. |x.. x..| = E What is your conclusion? 0 There is a signicant difference between the population means for the comfort levels of nonbrowsers and light browsers. 0 There is not a signicant difference between the population means for the comfort levels of nonbrowsers and light browsers. 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 Heavy Nonbrowser Browser Browser 4 5 5 5 6 7 6 5 5 3 4 7 3 7 4 4 4 6 5 6 5 5 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. O HO: HNB = H LB = HHB Ha : HNB * HLB # HHB O Ho: At least two of the population means are equal. H: At least two of the population means are different. O HO: HNB * HLB * HHB Ha: HNB = MLB = HHB O HO: HNB = HLB = HHB H: Not all the population means are equal. O Ho: Not all the population means are equal. Ha: HNB = HLB = HHB Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to three decimal places.) p-value =
