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 = 2.3452, y = 4.2500, sy = 1.7986, and r= - 0.9412, determine the least-squares regression line. (c) Graph the least-squares regression line on the scatter diagram drawn in part (a). X 0 2 3 4 6 6 y 6.0 6.0 5.4 3.7 2.1 2.3 (a) Choose the correct graph below. O A. O B. O C. OD. X X 6 X Q> - O X
