Problem 10.6 Refer to the fuel efficiency data (Table 10.2).

(a) Calculate the least squares estimates βˆ0 and βˆ1 for the regression Model(Y = gpm |X = weight). Copy the scatter plot from Figure 10.3 and draw the graph of the estimated regression line y = βˆ0 + βˆ1x. Use the same axes on which you graphed the scatter plot.

(b) Compute the sample correlation, coefficient of determination, and error sum of squares.

(c) Compute the residuals and display the results in a format similar to that of Table 10.3.
