1. If you want to compare the profitability of stores in different locations, explain what variables you expect to use. Be certain to mention variables other than those discussed above in the restaurant example that might affect the stores profitability. Carefully explain what effect you expect from each variable you include. For each variable, do you expect that the estimated coefficient will be positive or negative? Mention the source from which you plan to obtain the data you will use.

2. Once you have an acceptable regression, explain how you plan to use the results to determine the profitability of the changes.
