Consider the following least squares specification between test scores and the student - teacher ratio: TestScore = 557.8 + 36.42 In (Income). According to this equation, a 1% increase income is associated with an increase in test scores of :A. 36.42 points B. cannot be determined from the information given here C. 0.36 points D. 557.8 points

If we increase the income by 1% that means that the new income would be 1.01 the before one and if we replace this we got:

And the net increase can be founded like this:

So then the net increase would be:

C. 0.36 points

Step-by-step explanation:

For this case we have the following linear relationship obtained from least squares between test scores and the student-teacher ratio:

If we increase the income by 1% that means that the new income would be 1.01 the before one and if we replace this we got:

And the net increase can be founded like this:

So then the net increase would be:

C. 0.36 points

correct answer:

b.(19,-2)

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
