Answer:
Option d.
Step-by-step explanation:
The equation of the line of least squares is given as
where is the yield of wheat (bushels per acre) and x is the rainfall (in inches).
We need to find the expected number of inches of rain if the yield is 60 bushels of wheat per acre.
Substitute in the given equation.
