(a) Use the Corner Homes Data." The variables are Price = selling price of a home, SQFT = square feet are of home, Corner = 1 if home is on a corner and 0 if home is not on a corner

(b) Create a new variable column that is the product of the SQFT and Corner variables. This will be an interaction variable. Create a new name for the storage column, and in the expression box enter SQFT*Corner. Then, do a multiple regression with Price as the response variable (y-variable) and the three variables SQFT, Corner, and the newly created interaction variable as the predictor variables (x-variables). Write the resulting sample regression equation as the answer to this part.

(c) Using the fact that corner homes have Corner = 1, determine the equation that relates price to SQFT for corner homes. (Substitute Corner = 1 into the equation that you wrote for part (b).

(d) Using the fact that non-corner homes have Corner = 0, determine the equation that relates price to SQFT for non-corner homes. (Substitute Corner = 0 into the equation that you wrote for part (b).
