Estimate the sample regression equation that enables us to predict the price of a sedan on the basis of its age and mileage Price = __ + __ Age + __ Miles 2. Interpret the slope coefficient of Age. (Choose the right answer) A. The slope coefficient of Age is −479.26, which suggests that for every additional year of age, the predicted price of car decreases by $479.26. B. The slope coefficient of Age is −0.08, which suggests that for every additional year of age, the predicted price of car decreases by $0.08. C. The slope coefficient of Age is −479.26, which suggests that for every additional year of age, the predicted price of car decreases by $479.26, holding number of miles constant. D. The slope coefficient of Age is −0.08, which suggests that for every additional year of age, the predicted price of car decreases by $0.08, holding number of miles constant. 3. Predict the price of a four-year old sedan with 67000 miles
