Complete parts (a) through (h) for the data below. X ON y1-4 (d) By hand, determine the least-squares regression line y=x +(0) (Round to three decimal places as needed.) (e) Graph the least-squares regression line on the scatter diagram. Choose the correct graph below. O A. OB. OC. O D. (f) Compute the sum of the squared residuals for the line found in part (b). (Round to three decimal places as needed.) (g) Compute the sum of the squared residuals for the least-squares regression line found in part (d). (Round to three decimal places 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 line in part (b) passes through the most points. The line in part (d) minimizes the sum of the squared residuals, thus being the best-fitting line. More
