The Distribution of Sample Means
... "For any population with a mean and a standard deviation of , the distribution of sample means for sample size n will approach a normal distribution with a mean of and a standard deviation of /sqrt(n) as n approaches infinity." 1. it describes the distribution of sample means regardless of sh ...
