Consider the following partial computer output from a simple linear regression analysis.  Write the equation of the least squares line.
A)ŷ = 1.12 - 28.13x 
B)ŷ = -28.13 + 1.12 
C)ŷ = -28.13 + 1.12x 
D)ŷ = 1.12 + .04891x

Quizplus · Accepted Answer

The equation of the least squares line is represented as ŷ = b0 + b1x, where b0 is the y-intercept and b1 is the slope. From the given computer output, we can see that the intercept (b0) is -28.13 and the slope (b1) is 1.12. Therefore, the equation of the least squares line is ŷ = -28.13 + 1.12x, which corresponds to choice C.
