Natural Resources Canada measures fuel efficiency and other characteristics of vehicles. The data file called canfuel gives data for 1045 modelyear 2018 conventional vehicles. Variables include city and highway fuel efficiency measured in miles per imperial gallon (MPGCity and MPGHwy).

Let's examine the relationship between the two measures of fuel efficiency in the data set, highway MPG and city MPG.

(a)Use the city MPG to predict the highway MPG. Determine the equation of the leastsquares regression line. Give the slope and the intercept of the line.

(Use decimal notation. Give your answers to four decimal places.)

slope: _____________

intercept: ______________

(b)Find the city MPG and the highway MPG for the Honda CRV. Use your equation to find the predicted highway MPG for this vehicle.

(Use decimal notation. Give your answer to three decimal places.)

predicted highway MPG: _______________

(c)Find the residual.

(Use decimal notation. Give your answer to three decimal places.)

residual: ____________
