## content area top Part 1 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 overbarequals3.6667, s Subscript xequals2.3381, y overbarequals3.9333, s Subscript yequals1.7049, and requalsnegative 0.9499, determine the least-squares regression line. (c) Graph the least-squares regression line on the scatter diagram drawn in part (a). x 0 2 4 4 6 6 y 5.9 5.7 4.4 3.5 1.9 2.2 Question content area bottom Part 1 (a) Choose the correct graph below. A. 0 6 0 6 x y A scatter diagram has a horizontal x-axis labeled from 0 to 6 in increments of 1 and a vertical y-axis labeled from 0 to 6 in increments of 1. The following six points are plotted, listed from left to right: (0,0.2), (2,0.4), (4,1.6), (4,2.6), (6,4.2), (6,3.8). All vertical coordinates are approximate. B. 0 6 0 6 x y A scatter diagram has a horizontal x-axis labeled from 0 to 6 in increments of 1 and a vertical y-axis labeled from 0 to 6 in increments of 1. The following six points are plotted, listed from left to right: (0,6), (2,5.8), (4,4.4), (4,3.6), (6,2), (6,2.2). All vertical coordinates are approximate.
