(b) Find the equation of the line containing the points (9,136) and (18,119). y-x+ (Round to two decimal places as needed.) (c) Graph the line found in part (b) on the scatter diagram. Choose the correct graph below. OA 160 140- 120 100- 804 t G OB. 180 160- 140 120- 100 804 to O C. 160 140- 120- 100- 80- 15 10 10 10 C O D. 160-4 140- 120- 100- 804 500 o o
(d) Determine the least-squares regression line. (Round to two decimal places as needed.) (e) Graph the least-squares regression line on the scatter diagram. Choose the correct graph below.

(f) Compute the sum of the squared residuals for the line found in part (b), (Round to the nearest integer as needed.) (g) Compute the sum of the squared residuals for the least-squares regression line found in part (d). (Round to the nearest integer as needed.) (h) Comment on the fit of the line found in part (b) versus the least-squares regression line found in part (d). The sum of the squared residuals for the line found in part (b) is provides a measure of the sum of the squared residuals for the least-squares regression line found in part (d). Since the sum of the squared residuals
