Math Problem Statement

The _______ tells us that for a population with any distribution, the distribution of the sample means approaches a normal distribution as the same size increases

Solution

The Central Limit Theorem tells us that for a population with any distribution, the distribution of the sample means approaches a normal distribution as the sample size increases. This fundamental theorem is a cornerstone of statistics, emphasizing that the sampling distribution of the mean becomes approximately normal, regardless of the population's shape, provided the sample size is sufficiently large.

Tip: A common guideline is that a sample size of 30 or more is typically sufficient for the Central Limit Theorem to hold, but smaller sizes may suffice if the population distribution is not highly skewed.
