You decide to carry out an experiment in a sample of 24 stores where customer counts have been running almost exactly at the national average of 900. In 6 of the stores, the price of a small coffee will now be $0.59, in 6 stores the price of a small coffee will now be $0.69, in 6 stores, the price of a small coffee will now be $0.79, and in 6 stores, the price of a small coffee will now be $0.89. After four weeks of selling the coffee at the new price, the daily customer counts in the stores were recorded and stored in CoffeeSales 1. Analyze the data and determine whether there is evidence of a difference in the daily customer count, based on the price of a small coffee. 2. If appropriate, determine which mean prices differ in daily customer counts. 3. What price do you recommend for a small coffee?
