Question

Exercise 9 (page 160 ) 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 $\hat{y}=11.058-0.01466 x$. Would it be appropriate to use the regression line to predict $y$ from $x$ ? Justify your answer.
