A chain of clothing stores wants do develop a model that can predict sales based the store's location. A sample of past December sales in the four stores is given below

Store	2011	2010	2009	2008	2007
1	31	41	39	36	32
2	24	31	34	28	23
3	54	60	57	52	62
4	34	42	40	46	47

1. How many independent variables are needed in this problem?

2. Identify the coding scheme (introduce dummy variables and define them).

3. Propose a model that can show this relationship.

4. Fit the model to the data of the problem.

5. Make interpretation of all coefficients in the problem.
