A study was recently performed by an agency in which it attempted to develop a regression model to explain variation in highway mileage ratings of new cars. At one . . . _ 1, if standard transmission stage of the analySIs, the estimate of the model took the form below. where x1 represents the vehicle welght and x2 = . Complete parts a 0, if automatic transmission through e. 37: 34.11 0.004x1 + 4.34x2 c. Present an estimate of a model that would predict the average highway mileage rating for an automobile with a standard transmission as a function of the vehicle's weight. 9=I +( E (Simplify your answers. Type integers or decimals.) d. A certain automobile with automatic transmission weighs approximately 4,396 pounds. Provide an estimate of the average highway mileage you would expect to obtain from this model. El (Type an integer or a decimal.) e. Discuss the effect of a dummy variable being incorporated in a regression equation like this one. Use a graph if it is helpful. Choose the correct answer below. O A. Incorporating the dummy variable essentially gives two regression equations with the same intercept but different slopes depending on the weight of the vehicle. 0 B. Incorporating the dummy variable essentially gives two regression equations with the same intercept but different slopes depending on the type of transmission. 0 C. Incorporating the dummy variable essentially gives two regression equations with the same slope but different intercepts depending on the type of transmission. 0 D. Incorporating the dummy variable essentially gives two regression equations with the same slope but different intercepts depending on the weight of the vehicle
