The 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 1 2 3 4 5 6 7 8 9 10 Coke Classic 42 133 131 50 148 33 64 210 106 86 New Coke 6 110 54 12 43 11 34 160 57 147 Pepsi 33 95 105 45 45 45 76 122 79 96 Two-way ANOVA: Cans versus Drink, Building Source DF SS MS F P Drink 2 7, 208.5 3, 604.23 4.59 . 024 Building 9 51 , 209.2 5, 689 .91 7. 25 . 000 Error 18 14 , 132.2 785 . 12 Total 29 72 , 549.9Descriptive Statistics: Cans Variable Drink Mean Cans Coke Classic 100.3 New Coke 63.4 Pepsi 74. 1(b) What is the Tukey simultaneous 95 percent confidence interval for the following?
