A sample of 12 cars was taken, and the horsepower to miles per gallon was recorded. The computer output for regression is below:

A: y = 6.28 +0.07x
B: y= 0.07 + 6.28x
C: y = 7.47 -2.85x
D: y = -0.20 + 46.92x
E: y = 46.92-0.20x​

Respuesta :

Answer:

From the given output, the regression equation for the line is

ycap = 46.92 - 0.20x

Option D

MrRoyal

The regression equation of the sample of 12 cars from the computer output is (e) y = 46.92 - 0.2x

How to determine the regression equation?

From the computer output, we have the following parameters

Intercept = 46.92

Horsepower = -0.20

The above means that the regression equation is:

y = Horsepower * x + Intercept

So, we have:

y = -0.2x + 46.92

Rewrite as:

y = 46.92 - 0.2x

Hence, the regression equation of the sample of 12 cars is (e) y = 46.92 - 0.2x
