Problem 1.79 Refer to the fuel efficiency data set of Problem 1.76.

(a) Draw the scatter plot of gpm (y) vs. engine displacement (x).

(b) Calculate the least squares estimates b0 and b1 and draw the graph of the regression line y = b0 + b1x. Use the same axes on which you graphed the scatter plot.

(c) Compute the fitted values for x = 2.0, 3.8, 5.3.

(d) What is the effect on an automobile’s fuel efficiency (gpm) if its weight is increased by 0.5 liters?
