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 = 3.5000, s = 2.2583, y = 4.1000, sy = 1.7573, and r= - 0.9374, determine the least-squares regression line. (c) Graph the least-squares regression line on the scatter diagram drawn in part (a). X 1 3 4 6 6 0 y 5.0 6.4 5.3 3.6 2.0 2.3 .... . (a) Choose the correct graph below. O A. OB. O c. OD.
