(b) What is the Tukey simultaneous 95 percent confidence interval for the following? (Negative amounts should be indicated by a minus sign. Round your answers to 2 decimal places.) Confidence interval Coke Classic - New Coke 7.78 X 67.82 X Coke Classic - Pepsi (0.22) 59.82 V New Coke - Pepsi (38.02) X 22.02 XThe Coca-cola Company introduced New Coke in 1985. Within three months of this introduction, negative consumer reaction forced Coca-cola to reintroduce the original formula of Coke as Coca-cola Classic. Suppose that two years later, in 1987, a marketing research firm in Chicago compared the sales of Coca-cola Classic, New Coke, and Pepsi in public building vending machines. To do this, the marketing research firm randomly selected 10 public buildings in Chicago having both a Coke machine (selling Coke Classic and New Coke) and a Pepsi machine. The Coca-cola Data and a MINITAB Output of a Randomized Block ANOVA of the Data: Building 2 3 4 5 6 7 8 9 10 Coke Classic 45 136 134 41 146 33 71 224 111 87 New Coke 6 114 56 14 39 20 42 156 61 140 Pepsi 24 90 100 43 51 42 68 131 74 107 Two-way ANOVA: Cans versus Drink, Building Source DF SS MS F P Drink IN 7997.6 3998. 80 5 . 78 0 . 011 Building 55573.5 6174.83 8.93 0 . 000 Error 18 12443.7 691.32 Total 29 76014. 8 Descriptive Statistics: Cans Variable Drink Mean Cans Coke Classic 102.8 New Coke 64.8 Pepsi 73.0 (a-1) Calculate the value of the test statistic and p-value.
