I am considering clarifying the sentence "If the sampling fraction is less than 5% or 0.05, then the finite population multiplier might be ignored." by replacing it with:

A sampling fraction value close to one may occur if the sample size is relatively close to the population size. When sampling from a finite population without replacement, this may cause dependence between individual samples. To correct for this dependence when calculating the sample variance, a finite population correction (or finite population multiplier) of (N-n)/(N-1) may be used. If the sampling fraction is small, less than 0.05, then the sample variance is not appreciably affected by dependence, and the finite population correction may be ignored.
