D)n = 8 and N = 800.

Question

Quizplus · Accepted Answer

The finite population correction factor (FPCF) can generally be ignored when the sample size, n, is less than 5% of the population size, N. In option D, n = 8 and N = 800, which means the sample size is exactly 1% of the population size, fitting the criterion to ignore the FPCF.
