1) The sampling distribution of a statistic is the distribution that is formed using the computed statistic from a every possible sample, only of a given size, taken from the population.
2) The mean of the sampling distribution of a sample mean equals the population mean divided by the square root of the sample size.
3) The standard deviation of the sampling distribution of a sample mean equals the population standard deviation divided by the square root of the sample size.
4) When the population is not normal, if the sample size n ≥ 30, the sampling distribution of a sample mean is approximately normal.
5) The mean of the sampling distribution of a sample proportion equals the population proportion.
6) The standard deviation of the sampling distribution of a sample proportion equals the population standard deviation.
