What the heck is the t critical value for a t with 7 degrees of freedom in a 97% confidence interval? When I need them I usually just look them up in a book I have, but this book doesnt include 97%. Help me Obi Wan Kenobi, your my only hope.

This might help.

heh I was actually looking at that same table earlier, it doesnt appear to have the 97% values though. I did use google and went through pages of results but couldnt find anything

I guess it depends on how accurate you want to be, and if you just want to try working from 95% plus a fudge...

Didn't we have a post like this a month ago, in the same exact nature? I could just be going nuts though.

Just calculate it from the formula. You just need to compute the gamma and beta functions.

I tried for a while to see if Excels statistics functions could get me this, but then I had to get back to work. The help file for Excel does have the full formulas though, if you need that ref.
