Answer: The correct answer is A) can be calculated by subtracting the fitted values from the actual values.

Step-by-step explanation:

A. it can be calculated by subtracting the fitted values from the actual values.

(y=y^+resid) so, resid=y-y^ Yes.

B.can be calculated using the errors from the regression function.

(y=β0+β1x+e is unknown)

can be calculated using the errors from the regression function.

(y=β0+β1x+e is unknown)

C. are unknown since we do not know the population regression function. (y=β0+β1x+e is unknown, but we need resid)

D. should not be used in practice since they indicate that your regression does not run through all your observations.
