A real estate association in a suburban community would like to study the relationship between the size of a single-family house (as measured by the number of rooms) and the selling price of the house(in thousands of dollars). The study is to be carried out into different neighborhoods, one on the east side (= 0) of the community and the other on the west side (= 1). A random sample of 20 houses was selected with the results above.

Describe the linear regression equation.

a) Y^ = 43.737 + 9.219X1
b) Y^ = 43.737 +12.697X2
c) Y^ = 43.737 + 9.219X1 + 12.697X2.
