In chapter 8, we learned standard error of the mean ( read sigma xbar in denotation) or standard deviation of sample mean.Let's say the size(n) of the sample collected from a infinite population is greater than 1.

Compare "thestandard error of the mean "with"the standard deviation of X, population ".Which is smaller?Why?Explain conceptually or/and algebraically.Think of formula for Standard error of the mean (sigma xbar).
