The Central Limit Theorem

1、The mean of the sampling distribution is identical to the population mean.

2、The standard deviation of the distribution of sample means is equal to (sigma) / (the square root of N).The quantity is known as the standard error of the mean.

3、Provided that N is large enough,the shape of the sampling distribution is approximately normal.
