Exercise 9 1. A farmer wanted to find the relationship between the amount of fertilizer used and the yield of corn. He selected seven acres of his land on which he used different amounts of fertilizer to grow corn. The following table gives the amount of fertilizer (in pounds) used and the yield of corn (in bushels)for each of the seven acres. Fertilizer Used (x) 120 80 100 70 88 75 110 Yield of Corn(y) 138 112 129 96 119 104 134 a. Find the least squares regression line. a. Calculate r and r2
