The Mean Height for a Population of People Is 65 $\bar { x }$

Essay

The mean height for a population of people is 65 inches. Suppose that you pick a sample of 50 people and determine the sample mean, $\bar { x }$ . You then repeat this procedure three more times. You learned in class that $\mu _ { - \bar { x } } = \mu$ . Can you conclude that the mean of the four sample means will be equal to the population mean of 65 inches? Why or why not?
