The central limit theorem (CLT) is generally valid for:
A) n > 5
B) n > 10
C) n > 20
D) n > 30
E) any size n

Quizplus · Accepted Answer

The central limit theorem is generally valid for n > 30, meaning that as long as the sample size is larger than 30, the sample mean will follow a normal distribution even if the population distribution is not normal. However, this rule of thumb may vary depending on the shape of the population distribution, so it is always best to verify the validity of the CLT for a specific case.
