Problem 15

Home prices Many variables have an impact on determining the price of a house. A few of these are Size of the house (square feet), Lotsize, and number of Bathrooms. Information for a random sample of homes for sale in the Statesboro, Georgia, area was obtained from the Internet. Regression output modeling the Asking Price with Square Footage and number of Bathrooms gave the following result: Dependent Variable is Asking Price s = 67013 R-Sq = 71.1, R-Sq (adj) = 64.6, Predictor Coeff SE(Coeff) t-Ratio P-Value Intercept -152037 85619 -1.78 0.110 Baths 9530 40826 0.23 0.821 Sq ft 139.87 46.67 3.00 0.015 Analysis of Variance Source DF SS MS F-Ratio P-Value Regression 2 99303550067 49651775033 11.06 0.004 Residual 9 40416679100 4490742122 Total 11 1.39720E+11 a) Write the regression equation. b) How much of the variation in home asking prices is accounted for by the model? c) Explain in context what the coefficient of Square Footage means. d) The owner of a construction firm, upon seeing this model, objects because the model says that the number of bathrooms has no effect on the price of the home. He says that when he adds another bathroom, it increases the value. Is it true that the number of bathrooms is unrelated to house price? (Hint: Do you think bigger houses have more bathrooms?)
