\fA statistical program is recommended. The Honda Accord was named the best midsized carfor resale value for 2013 by the Kelley Blue Bouk.T The file AutoResale oorltalns mileage, age, and selling price for a sample of 33 Honda Accords. Use the estimated regression equation diet predicts the selling price of a used Honda Accord given the mileage and age ofle car to answer the following questions. (tetxL represent the mileage of die oar, x2 represent the age of die ear, and y represent the selling price of the ear.)
