Random samples of size 64 are taken from an infinite population whose mean and standard deviation are 24 and 6.4, respectively. The distribution of the population is unknown. What are the mean and the standard error of the sample mean?
Added by Joseph M.
Step 1
So, the mean of the sample mean is 24. Second, the standard error of the sample mean is the standard deviation of the population divided by the square root of the sample size. So, the standard error of the sample mean is 6.4 divided by the square root of 64, Show more…

A sample of n = 64 scores is selected from a population with μ = 80 and with σ = 24. On average, how much error is expected between the sample mean and the population mean?
