Select the statement that best describes the relationship between an actual average sample mean versus theoretical average sample mean. 1. The actual average sample mean will almost never be exactly equal to the theoretical average sample mean, because random samples are, as their name implies, random. Over the course of many samples, the average sample mean will not approach the theoretical value. 2. The actual average sample mean will almost never be exactly equal to the theoretical average sample mean,...

A random sample of n=25 individuals is selected from a population with mean =20, and a treatment is administered to each individual sample. After treatment, the sample mean is found to be M=22.2 with as=384. If there is no treatment effect, how much difference is expected between the sample mean and it's population mean. Find the standard error for M.
