Answer 1

From the given table, let, х be right arm and y be left arm. then, to find regression equation we = و at bo SP where, ba a = My-bmx SS My Mean of Y = 154,6 Mх Mean of x = 89.2 SP = sum of products = 733:4, ssx = sum of squares of x = 930.5 SP o 78 792 b= 733.4 930,8 SSX My - bmx = 154,6-(0.78792 * 89-2) a= 84-317 ... Regression ssion equation is, ។ = 84.317 +0,7879 X For X = 90 ŷ = 84,317 + 0.7879 690), 155.23
