Sampling Distribution of Sample Mean
... • CLT states that for randomly selected sample size (n should be at least 25, but the larger n , the better the approximation) with a mean (μ) and standard deviation ( ): 1. The mean of the distribution of sample means is equal to the mean of the population distribution (μ (x) = μ ). 2. The standar ...

If we were to take all possible samples of the same size from the population and compute the sample proportion, p̂ , of each sample and then create a distribution it would be called a sampling distribution of p̂ . The following properties generally describe a sampling distribution created from sampl ...
