Question 2

Explain why the result for possible magnitudes of the finite population correction factor,
 
  for samples of n =15 observations from populations of N = 15, 30, 60, 100, 500, 1,000, 5,000, and 10,000 members, is precisely what one should expect on intuitive grounds.

Answer to Question 1

D

Answer to Question 2

When the population size (N) equals the sample size (n), then there is no variation away from the population mean and the standard error will be zero. As the sample size becomes relatively small compared to the population size, the correction factor tends toward 1 and becomes less significant in the calculation of the standard error.
