Consider a population of 5 weights identical in appearance but weighing 1, 3, 5, 7, and 9 ounces.

A. Determine the mean and the variance of the population.
B. Sampling without replacement from the above population with a sample size of 2 produces ten possible samples. Using the ten sample mean values, determine the mean of the population and the variance of .
C. Compute the standard error of the mean.
