Recall that if we use the finite-population-correction (FPC) factor, the complete expression for the margin of sampling error for SRS would be Solve this for n, writing such end result as , where Notes: The was added to to indicate "for finite population (of size 1)". [Also, as indicated two lessons ago, notice as, goes to the original , which shows it is the absolute sample size (n) and not the relative sample size (n/N) that determines practically the entire precision in estimation (E) when N is large (N>>n, or, as usually used by many persons, N>20n).] Important Hint: Since N and N-l are practically the same, start by replacing the N - 1 by N.
