Help!!

Is there a way to enter the population of a sampling distribution into the TI-83 and pull the means, variances, etc, for each sample?

For example:

A population consists of the numbers 11, 28, 46 and 63. Pull two samples (n=2) and compare the mean and probability of each possible combination.

Right now I'm doing it by hand: (11,11) (11,28) (11,46) (11,63) (28,11) (28,28) etc etc for all 16 sets and finding the mean, probability, and variance for each one. But it seems to me that something as smart as my TI, there should be a function where I can plug in each number in the population and it will do all the grunt work for me. Or no?

Google didn't come up with anything, and it's possible I wasn't entering the correct search terms.

Doubtful..

83 is a graphing calculator heavy on calculus..

Our stats and probablitiy (if I remember right) we used excel and an add on called "Solver"

We have a program called MiniTab, but it's for the computer and will not help me on a test.

Is anything you were trying to do covered here - TI-83/84/89/92 Procedures and Help (TC3, Brown)

I don't think so. That tells me how to put them all into a list and calc the statistics for the list, but doesn't break them down by sample size. But I did just see that there's a way to get the variance with a couple of clicks instead of squaring the standard deviation and screwing it up.
