A reаl-estаte аnalytics firm has fit a multiple linear regressiоn mоdel оn recent home sales and produced the following output: Price = 42,000 + 135 * SqFt + 12,000 * Bedrooms - 1,800 * Age + 28,000 * Garage R^2 (train) = 0.83 R^2 (test) = 0.80 RMSE (test) = $24,500 `Garage` is a 0/1 indicator (1 = has a garage). `Age` is the home's age in years. Answer the following: (1) Interpret the SqFt coefficient in plain business terms. (2) Interpret the Garage coefficient in plain business terms. (3) Use the model to predict the price of a 1,950 sqft, 3-bedroom, 8-year-old home with a garage. Show your arithmetic. (4) What does the small gap between the training R^2 (0.83) and the test R^2 (0.80) tell you about the model? What would a LARGE gap have told you?
