The results are shown in the table. Determine the least squares regression line for the data using the regression capabilities of a graphing utility, and then use this model to estimate the yield for a fertilizer application of 160 pounds per acre. Round your answer to one decimal place.

A) 37.3 bushels per acre
B) 39.7 bushels per acre
C) 35.6 bushels per acre
D) 38.4 bushels per acre
