Suppose an Agronomist Used Four Test Plots to Determine the Relationship

question 2

Multiple Choice

Suppose 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 hundreds of pounds per acre) . 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
