F distribution on the 41C

This would require a t-test – and maybe that's the solution for the following problem:

Ah, the good old 224 byte limit – I remember the days when I used the card reader more often than I do now. I think we don't get this program below this limit without sacrificing relevant functionality. So the solution might be another one: expand it (!), so that it fills two cards. ;-)

I just did some slight improvements, it's about 200 lines now. But now that we have a regularized Beta function: what about adding Student's t distribution? It can be evaluated easily using the same Beta function. And it allows to test the significance of means two from different samples. ;-)

Two cards with Fisher's F and Student's t distribution don't sound like a bad idea to me. And later you may add two more cards for the Normal and Chi² distribution, both based on the regularized Gamma function.
