C)subtracting the mean of Y from the overall mean of X.
D)any of the above

Quizplus · Accepted Answer

The conditional mean of Y for any value of X is found by taking all the Y scores corresponding to that specific value of X, adding them up, and then dividing by the number of observations (N) corresponding to that specific value of X. This is the definition of the conditional mean and is represented mathematically as E(Y|X=x) = ΣY/N. Therefore, choice A is the correct answer. The other options are not accurate representations of how to find the conditional mean of Y for any value of X.
