Subject:   BASIC STATISTIC QUESTION
Content-type:   text/plain; charset=us-ascii

I have a sample of data and am asked to find the mean, E(X), E(X**2), and STD(X). example of the data is as follows:

$1,235.34 $500.23 $220.35

it's been quite awhile since i've had a statistics course. i imagine that i can use SAS to complete this, however i'd like to understand the formulas as well. can anyone help me figure this one out by hand for this data? thank you!!!
