Suppose N=80,000, n=20,000, and s=50.
a. Compute the standard error of x using the finite population correction factor. Round to four decimal places.
b. Repeat part a assuming n = 40,000
c. Repeat part a assuming n = 80,000
d. Compare parts a, b, and c, and describe what happens to the standard error of x (with a line over it) as n is increased.
