# Agriculture An agronomist used four test plots to determine the relationship between the wheat yield y (in bushels per acre) and the amount of fertilizer x (in pounds per acre). The results are shown in the table. Fertilizer, x 100 150 200 250 Yield, y 35 44 50 56 (a) Use the regression capabilities of a graphing utility or a spreadsheet to find the least squares regression line for the data.(b) Estimate the yield for a fertilizer application of 160 pounds per acre.
