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, sy = 2.3452, y = 3.9833, sy = 1.8126, and r= - 0.9480, determine the least-squares regression line. (c) Graph the least-squares regression line on the scatter diagram drawn in part (a). O X > 5.8 5.7 5.1 3.5 1.8 2.0 O A. O B. O C. OD. O x 1 There appears to be a linear, negative relationship. (b ) y = ]x + () (Round to three decimal places as needed.) (c) Choose the correct graph below. O A. OB. O C. OD
