Web31 de mar. de 2024 · Normal Distribution: If independent normal samples of the same size, n, are repeatedly collected from a population, which can have any distribution, meaning different sample series but with the same sample size n, then the distribution of the mean of the samples for a sample size is approximately normal. If the randomly …
