The data in the table represent the weights of various domestic cars and their miles per gallon in the city for the 2008 model year. For these data, the least-squares regression line is y = – 0.005x+ 38.154. A twelfth car weighs 3,425 pounds and gets 12 miles per gallon.

- ov The scatterplot below shows the relationship between mass, x, in kilograms of a car and its fuel efficiency, y, in miles per gallon. The least-squares line is also shown on the scatterplot. The equation of the least-squares line is ŷ = 37.335 -0.00965x. Find the predicted and residual gas mileage for a car that weighs 1,500 kilograms and has a gas mileage of 20 miles per gallon.
