Hello!

I'm having trouble with this practice problem. I figured out Part A, but I'm confused when it comes to Part B.

Part A

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 5 4 5 5 7 7 6 5 7 3 4 3 7 4 6 5 6 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. HO: HNB = PLB = UHB He: Not all the population means are equal. O Ho: HNB = HLB = UHB Ha: HNB * HLB # HHB O HO: HNB * HLB * HHB Ha: HNB = MLB = HHB O Ho: Not all the population means are equal. Ha: HNB = HLB = HHB O Ho: At least two of the population means are equal. Ha: At least two of the population means are different. Find the value of the test statistic. (Round your answer to two decimal places.) 3.68 Find the p-value. (Round your answer to three decimal places.) p-value = 0.043(b) Use Fisher's LSD procedure to compare the comfort levels of nonbrowsers and light browsers. Use a = 0.05. Find the value of LSD. (Round your answer to two decimal places.) LSD = Find the absolute difference between sample means for the comfort levels of nonbrowsers and light browsers. INB - What is your conclusion? O There is a significant difference between the population means for the comfort levels of nonbrowsers and light browsers. There is not a significant difference between the population means for the comfort levels of nonbrowsers and light browsers
