b. Calculate the sum of squares error for the following equations: (1) y= 1.1 +0.7x, (2) y=2.0+ 1.3x, and (3) y= 1.7 + 0.1x. The sum of squares error for the equation y = 1.1 +0.7x is The sum of squares error for the equation y=2.0+ 1.3x is The sum of squares error for the equation y = 1.7 + 0.1x is (Round to two decimal places as needed.) c. Which of these equations provides the "best" fit of these data? Describe the criterion used to determine "best" fit. O A. The equation y=2.0 +1.3x provides the best fit because it has the lowest sum of squares error. This criterion is called the method of least squares. O B. The equation y= 1.1 +0.7x provides the best fit because it has the lowest sum of squares error. This criterion is called the method of least squares. O C. The equation y= 1.7 + 0.1x provides the best fit because it has the lowest sum of squares error. This criterion is called the method of least squares. O D. The equation y= 2.0 + 1.3x provides the best fit because it has the highest sum of squares error. This criterion is called the method of most squares. O E. The equation y = 1.1 + 0.7x provides the best fit because it has the highest sum of squares error. This criterion is called the method of most squares. O F. The equation y= 1.7 + 0.1x provides the best fit because it has the highest sum of squares error. This criterion is called the method of most squares. d. Determine the regression line that minimizes the sum of squares error. -ロ+Dx 口口口
