Document Summary
Econ 2500 winter 2011 xianghong li. Chapter 5 sampling distributions mar 1. The word selection is used, when the order of things has no importance: e. g. abc and cba is the same combination but different permutation. A population contains proportion p of successes. If the population is much larger than the sample, the count x of successes in a srs of size n has approximately the binomial distribution b (n, p). The accuracy of this approximation improves as the size of the population increases relative to the size of the sample.
