Problem #5: Given the following five pairs of (x, y) values, 11 6 13 X 1 4 y 10 7 44 0 Problem #5(a): Problem #5(b): (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., (1, 10) and (4,7)] are above the regression line, then since the sum of the two corresponding y-values is 10+7=17, you would enter 17 into the answer box. enter the values of bo and b (in that order), separated by a comma (numbers correct to 4 decimals) sum of y-values for points above the regression line Just Save Submit Problem #5 for Grading Problem #5 Attempt #1 Attempt #2 Attempt #3 Your Answer: 5(a) 5(a) 5(a) 5(b) 5(b) 5(b) Your Mark: 5(a) 5(a) 5(a) 5(b) 5(b) 5(b)
