Suppose you have two populations: Population A-All students at Illinois State University (N = 21,000) and Population B-All residents of the city of Homer Glen, IL (N = 21,000). You want to estimate the mean age of each population using two separate samples each of size n = 75. If you construct a 95% confidence interval for each population mean, will the margin of error for population A be larger, the same, or smaller than the margin of error for population B? Justify your reasoning.
