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 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 24 90 100 43 51 42 68 131 74 Pepsi 107 Two-way ANOVA: Cans versus Drink, Building Source SS MS F P Drink 7997.6 3998.80 5.78 0.011 Building DO CON 65573.5 6174.83 8.93 0.000 Error 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.
