A data set is given below. K (a) Draw a scatter diagram. Comment on the type of relation that appears to exist between x and y. (b) Given that x = 3.5000, S = 2.5100, y = 4.4167, sy = 1.6510, and r= - 0.9484, determine the least-squares regression line. (c) Graph the least-squares regression line on the scatter diagram drawn in part (a). X 0 1 4 4 6 6 y 6.0 6.5 4.8 3.9 2.4 2.9 . . . (a) Choose the correct graph below. O A. &B. O c. O Ay Ay 7-7 7 7 There appears to be a linear, negative relationship. (b ) y = x + (D (Round to three decimal places as needed.)
