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: 1 2 3 Building 4 5 Coke Classic 50 144 139 41 142 New Coke 9 109 53 53 31 Pepsi 21 97 109 38 59 10000 1 6 28 28 46 1788000 8 9 10 77 225 109 81 39 147 52 144 68 125 80 101 Two-way ANOVA: Cans versus Drink, Building Source DF SS MS F Drink 2 8,909.6 4,454.80 5.60 Building 9 52,905.5 5,878.39 7.39 P .013 .000 Error 18 14,309.7 794.99 Total 29 76,124.8 Descriptive Statistics: Cans Variable Cans Drink Mean Coke Classic 103.6 New Coke 62.6 Pepsi 74.4 (a-1) Calculate the value of the test statistic and p-value.
