Submit test a. Using the pairs of values for all 10 points, find the equation of the regression line. b. After removing the point with coordinates (1,3), use the pairs of values for the remaining 9 points and find the equation of the regression line. 10 c. Compare the results from parts (a) and (b). 4- a. What is the equation of the regression line for all 10 points? y =+x(Round to three decimal places as needed.) b. What is the equation of the regression line for the set of 9 points? y = (Round to three decimal places as needed.) c. Choose the correct description of the results below. O A. The regression line changes, but the change is small. O B. The regression line is very similar in both cases. O C. The removal of the point has a significant impact on the regression line. O D. There is no regression line for the second case because the data are in a pattern.
