K 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 = 3.8333, S = 2.4014, y = 3.9167, sy = 1.8324, and r = - 0.9446, determine the least-squares regression line. (c) Graph the least-squares regression line on the scatter diagram drawn in part (a).
