is the mean and n is the number of observations.
Sum of squares of differences =
Thus, the correct answer is
All values are identical.
If
then the derivative is
Critical points occur where . This happens for
In the first case, we find
In the second,
So all the critical points occur at multiples of , or
. (This includes all the even multiples of
.)
