A data set is given below. (a) Draw a scatter diagram. Comment on the type of relation that appears to exist between x and y. (b) Given that x = 3.8333, s = 2.0412, y = 4.2333, sy = 1.4556, and r = - 0.9065, determine the least-squares regression line. (c) Graph the least-squares regression line on the scatter diagram drawn in part (a). X 1 2 4 4 6 6 0 y 5.3 6.1 4.9 3.9 2.4 2.8 O A. O B. O C. OD.
