Outcome 2 ANOVA: A consumer preference study compares the effects of three different bottle designs (A, B, and C) on sales of a popular fabric softener. A completely randomized design is employed. Specifically, 15 supermarkets of equal sales potential are selected, and 5 of these supermarkets are randomly assigned to each bottle design. The number of bottles sold in 24 hours at each supermarket is recorded. The data obtained are displayed in the following table, Anova: Single Factor Groups Count Sum Average Variance 5 16.6 32.8 9.2. 124 A 5.3 83 164 B 5 с 5 24.8 8.2 SS df MS F Fcrit ANOVA Source of Variation Between Groups Within Groups P-value 0.00 2 90.8 Total 746.933 Complete the table above: Complete the table above. 1.
