Given the following five pairs of (x,y) values, x 05 11 8 13 y 10 8 5 3 1 (a) Determine the least squares regression line. (Be sure to save your unrounded values of bo and b for use in Problem #6 below.) (b) Draw the least squares regression line accurately on a scatterplot. Then look to see which (x,y) pairs are above the regression line. Then add up the y-values for all of the (x,y) pairs that fall above the regression line. For example, if you draw your least squares regression line accurately on a scatterplot, and you find that the first two (x, y) pairs [i.e., (0, 10) and (5,8)] are above the regression line, then since the sum of the two corresponding y-values is 10 + 8 = 18, you would enter 18 into the answer box.
