The central limit theorem states that regardless of the distribution of the population, as the sample size increases, the distribution of sample means approximates a normal distribution with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size. This allows researchers to use the standard normal distribution to estimate the probability of selecting sample means.
