OC D. 20- 20- 20- 20- Q 10 10 40 (b) By hand, compute the correlation coefficient. The correlation coefficient is r= 0.935 . (Round to three decimal places as needed.) (c) Determine whether there is a linear relation between x and y. Because the correlation coefficient is |positive and the absolute value of the correlation coefficient, 0.935 , is not greater than the critical value for this data set, 0.997 no linear relation exists between x and y.
