skelet666 [1.2K]

Answer:

Option d.

Step-by-step explanation:

The equation of the line of least squares is given as

$\hat{y} = -9.12+ 4.38x$

where $\hat{y}$ 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 $\hat{y}=60$ in the given equation.

$60= -9.12+ 4.38x$

Add 9.12 on both sides.

$60+9.12=4.38x$

$69.12=4.38x$

Divide both sides by 4.38.

$\frac{69.12}{4.38}=x$

$x\approx 15.78$

The expected number of inches of rain is 15.78.

Therefore, the correct option is d.
