I've been trying, with no success, for the past few hours to find a way to keep calculations done in the TI-89's "Stats/List Editor" in exact form instead of decimal. For example, when I enter the following information:

I get:

Where I want p1_hat to be 22/36, p2_hat to be 20/23, etc..

3. The attempt at a solution

I know in the older TI's you could do something like, Math->exact->p1_hat, and it would give it to you, but if I do Math->numbers->exact()->exact(statvars\p1_hat) I get the following:

If you know of a way or another program that I can download to get the exact forms, I'd be very grateful!
