You work in the corporate office for a nationwide convenience
store franchise that operates nearly 10,000 stores. The per-store
daily customer count has been study at 900 for some time (i.e., the
mean number of customers in a store per day is 900). To increase
the customer count, the corporate office is considering cutting
coffee prices. Even with this reduction in price, the franchise
will have a 40% gross margin on coffee. To evaluate the new
initiative, the franchise has reduced coffee prices in a sample of
34 stores that are randomly chosen. After four weeks of reduced
prices, the sample stores stabilize at a mean customer count of 974
and a standard deviation of 96. Is there a way to get a feel for
what the mean per-store count in all the stores will be if you cut
coffee prices nationwide? Do you think reducing coffee prices is
likely to increase mean customer count nationwide? Be specific.
Hint: Construct a suitable confidence interval.
