When the sample size is greater than around 40, the normal approximation of the sampling distribution of the mean is quite good. This is because of the Central Limit Theorem which states that as long as the sample size is large enough, the sampling distribution of the mean will be approximately normal regardless of the shape of the population distribution.

When the Sample Size Is Greater Than Around 40,the Normal
