Compute the relevant statistic and if the result is significant, indicate what is driving this effect. a. The significant difference across brands were driven by a significant difference in one pair of supplements. O b. The significant difference across supplements was because one brand was significantly different from the other two groups. c. There was no significant difference across groups. d. All three supplements were significantly different from each other. Three brands of health supplements are to be compared by testing each brand on a group of ten individuals. Thirty individuals are randomly selected and divided into three groups of ten each. Then each group receives a different brand of health supplement. The health outcomes, measured in a specific metric, for each group are as follows. Supp A Supp B Supp C 1.89 1.44 1.73 1.79 1.40 1.75 1.72 1.33 1.79 1.64 1.24 1.76 1.60 1.28 1.69 1.62 1.50 1.90 1.71 1.60 1.73 1.88 1.24 1.72 2.28 1.15 1.74 2.02 1.29 3.34
