To find the Z score for a sample's mean on the distribution of means, we need to use the standard formula for changing a raw score to a Z score, using the mean and standard deviation of the distribution of means. The mean of the distribution of means is the same as the population mean, and the standard deviation of the distribution of means (also known as the standard error) is equal to the population standard deviation divided by the square root of the sample size. Using this information, we can calculate the Z score for a sample's mean on the distribution of means.
