4. The following regression model has been estimated from a sample size of 42: P = 52.3510+ 0.1388S; + 15.3250C; P = home price in 000s of dollars, S = size of house in square feet, and C = 1 if the house is located in a cul-de-sac, 0 otherwise. Assume all the coefficients are statistically significant. (a) [3 points] How would you interpret bo (i.e., 52.3510)? (b) [3 points] On average, how much would a house with 2,000 square feet and located in a cul-de-sac cost? (c) [3 points] How much would it cost, on average, to get an additional 500 square feet?
