Finite Population Correction Factor For Formulas 7-2 and 7-3 we assume that the population is infinite or very large and that we are sampling with replacement. When we sample without replacement from a relatively small population with size N, we modify E to include the finite population correction factor shown here, and we can solve for n to obtain the result shown below. Use this result to repeat part

(b) of Exercise 36, assuming that we limit our population to a county with 2500 women who have completed the time during which they can give birth.
