Document Summary

Sampling distribution: a sampling distribution is created by, as the name suggests, sampling, the method we will employ on the rules of probability and the laws of expected value and variance to derive the sampling distribution. x. 2 = s where s xp x s s (cid:229)== m s n: sampling distribution of the sample mean. However, if the population is finite the standard error is n/s s x for infinitely large populations. s nn. N where n is the population size and population size is large relative to the sample size the finite population correction factor is close to 1 and can be ignored. is called the finite population correction factor. If the: as a rule of thumb we will treat any population that is at least 20 times larger than the sample size as large. In practice most applications involve populations that qualify as large.
