(b) Interpret the LS estimate of the regression coefficient for the log(Crime) term. (c) Refit the model in part (a) with an extra interaction term log(Crime) x log(Miles). Is the interaction between the two predictors significant at level o = 0.05? (d) Based on the model in part (c), for a community that is 12 miles away from Center City, Philadelphia, if the crime rate increases from 35 per 1000 to 42 per 1000, what impact do you expect it to have on the housing price in that community
