Extracted text: 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, = 2.5884, y = 4.3167, s, = 1.9467, and r= -0.9546, determine the least-squares regression line. (c) Graph the least-squares regression line on the scatter djagram drawn in part (a). 1. 6 6.0 6.7 5.4 3.1 2.2 2.5 5 6 y (a) Choose the correct graph below. O A OB. Oc. OD.
