What is the error of the mean of data that have uncertainty values attached to them?
One interpretation of your situation is that you have obtained a random sample $Y_1, \ldots, Y_n$ from a distribution with a finite variance, say $\sigma^2,$ but you have observed the values $X_i = ...

Is there a standard error of the mean for when population size is known?
Transcribing from comments.
For final populations there exists a correction factor which will probably useful for this purpose.
$FPC=\sqrt{(N-n)/(N-1)}$,
and the standard error formula becomes
$SE=s/\...
