... When the sample is large with respect to the population size ( n / N > 5 %): Eq. 1.4.14: 95% Confidence Interval for True Population Mean: = Sample Mean ± t (n - 1) *{[S / Sq. Rt. (n)]*[Sq. Rt.((N - n)/(N-1))]} where n = the sample size and N = the population size (the rule of thumb is n / N should ...
