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 have a relatively small population with size N and sample without replacement, we modify E to include the finite population correction factor shown here, and we can solve for n to obtain the result given here. Use this result to repeat Exercise, assuming that we limit our population to 200 particular passengers on a Boeing 757-200 ER aircraft.

In exercise

a. Assume that nothing is known about the percentage of passengers who prefer aisle seats.

b. Assume that a recent survey suggests that about 38% of air passengers prefer an aisle seat (based on a 3M Privacy Filters survey).

E = Zal27 VN - 1 p4[ zat2]? + (N - 1)E?
