Answer:

Option B

Step-by-step explanation:

Given that the regression equation using least squares for test scores and student teacher ratio is

Test Score = 557.8 + 36.42 In (Income).

Say if 1% income is increased.

Let income be 100

New income = 101

Then we have

Test score original =

557.8+36.42 Ln 100\\= 725.520

Test score new income

= 557.8+36.42 ln (101)\\= 725.882

Increase = 0.362~0.36

Option B is right.
