(Round your coefficient of determination to 4 decimal places. Round all other answers to 2 decimal places. Negative amounts should be indicated by a minus sign.) x 5 3 y 13 15 12 32 4 13 11 +1 4 y-y (x-2) (y-y) (x x) (y- y) 5 13 0.13 2.38 0.02 5.64 0.30 3 15 -1.88 67 1.13 4.38 -3.63 3.52 19.14 -8.20 1.27 13.14 -4.08 3 12 -1.88 1.38 3.52 1.89 -2.58 4 13 -0.88 2.38 0.77 5.64 -2.08 4 11 -0.88 0.38 0.77 0.14 -0.33 69 1.13 -1.63 1.27 2.64 -1.83 8 5 3.13 -5.63 9.77 31.64 -17.58 39 85 Total 20.88 79.88 -36.38 69 18 = 4.875 = 10.625 J . Sx 1.7268 Sy = 3.3779 r = -0.8909 The correlation coefficient of -0.89 indicates a very strong negative relationship between x and y. The coefficient of determination is found by squaring the value of the variation in y. . x accounts for % of
