For population distributions that are not heavily skewed, many statisticians consider a minimum sample size of to produce a sampling distribution of the mean that will approximate a normal distribution.
A)5
B)8
C)30
D)36

The central limit theorem states that for sample sizes greater than or equal to 30, the sampling distribution of the mean will be approximately normal, regardless of the shape of the population distribution. Thus, a minimum sample size of 30 is recommended to produce an accurate approximation of the sampling distribution of the mean. Choices A and B are too small, and choice D is unnecessarily large.
