he 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 46 133 123 41 152 35 62 217 122 86 New Coke 4 114 64 15 48 10 39 146 53 143 Pepsi 27 82 110 36 52 43 62 130 71 98 Two-way ANOVA: Cans versus Drink, Building Source DF SS MS F P Drink 2 8,147.4 4,073.70 5.68 .012 Building 9 53,434.8 5,937.20 8.28 .000 Error 18 12,914.6 717.48 Total 29 74,496.8 Descriptive Statistics: Cans Variable Drink Mean Cans Coke Classic 101.7 New Coke 63.6 Pepsi 71.1 (a-1) Calculate the value of the test statistic and p-value.
