An engineer wants to determine how the weight of a car, x, affects gas mileage, y. The following data represent the weights of various cars and their miles per gallon. Car A B C D E Weight (pounds), x 2590 3035 3435 3650 4170 Miles per Gallon, y 25.7 19.4 19.5 16 13.4 1 ) Predict the miles per gallon of car B and compute the residual. Is the miles per gallon of this car above average or below average for cars of this weight? The predicted value is ______ miles per gallon. (Round to two decimal places as needed.) 2) The residual is negative ______ miles per gallon. (Round to two decimal places as needed.)
