Subject:  BASIC STATISTIC QUESTION 
Contenttype:  text/plain; charset=usascii 

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!!!
