Calculate the correlation coefficient r, letting Row 1 represent the x-values and Row 2 the y-values. Then calculate it again, letting Row 2 represent the x-values and Row 1 the y-values. What effect does switching the variables have on r? Row 1 18 25 33 49 51 70 77 Row 2 204 172 107 202 106 171 174 . . . Calculate the correlation coefficient r, letting Row 1 represent the x-values and Row 2 the y-values. r=(Round to three decimal places as needed.)
