Question

Examlex · Accepted Answer

The Answer is The central limit theorem: for all samples of the same size

n

with

n > 30

, the sampling distribution of

\bar { x }

can be approximately by a normal distribution with mean

\mu

and standard deviation

\sigma / \sqrt { n }

. If an original population is not normally distributed, the distribution is approximately a normal distribution if

n > 30

.
