Answer:
Option d.
Step-by-step explanation:
The equation of the line of least squares is given as
![\hat{y} = -9.12+ 4.38x](https://tex.z-dn.net/?f=%5Chat%7By%7D%20%3D%20-9.12%2B%204.38x)
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.
![60= -9.12+ 4.38x](https://tex.z-dn.net/?f=60%3D%20-9.12%2B%204.38x)
Add 9.12 on both sides.
![60+9.12=4.38x](https://tex.z-dn.net/?f=60%2B9.12%3D4.38x)
![69.12=4.38x](https://tex.z-dn.net/?f=69.12%3D4.38x)
Divide both sides by 4.38.
![\frac{69.12}{4.38}=x](https://tex.z-dn.net/?f=%5Cfrac%7B69.12%7D%7B4.38%7D%3Dx)
![x\approx 15.78](https://tex.z-dn.net/?f=x%5Capprox%2015.78)
The expected number of inches of rain is 15.78.
Therefore, the correct option is d.
