Should it be near the front door of the grocery stores, in the cola section, at the checkout registers, or near the milk and other dairy products? Four stores with similar total sales cooperated in an experiment. In one store, the 12- packs were stacked near the front door, in another they were placed near the checkout registers, and so on. Sales were checked at specified times in each store for exactly four minutes. The results were: Cola at the Door In Soft Drink Section 7$ 11 Near Registers 6$ Dairy Section 12$ 9$ 10 11 10 12 10 12 14 7 12 The Buffalo distributor wants to find out whether there is a difference in the mean sales for cola stacked at the four locations in the store. Use the .05 significance level. 1. State the null and the alternate hypotheses. 2. What is the decision rule? 3. Find the ANOVA table. 4. State your decision regarding the null hypothesis. 5. Interpret the result.
