Question: Driving speed and fuel consumption, gives data on the fuel consumption y of a car at various speeds x. Fuel consumption is measured in liters of gasoline per 100 kilometers driven and speed is measured in kilometers per hour. A statistical software package gives the least-squares regression line and the residual plot shown below. The regression line is y^ = 11.058 - 0.01466x. Would it be appropriate to use the regression line to predict y from x? Justify your answer.
