I'm borrowing my friends TI-86 because I lost mine a while back. I'm using it in my Statistics class right now. I need to use nmcdf and invnm but I can't find it on here. I think it might have been deleted. How do I get it back on here?

Hey there,

You are looking for the cube root function which can be found under the MATH menu selection. the answer you get will simply need to be squared and you have your answer

The chi-square test is used for a lot more than just contingency tables.

I found one program for the TI-86 (which is basically the same machine as the TI-85, only with more memory) which claims to do the chi-square goodness of fit test.

I hadn't used mine in years and had the same problem. Essentially you just need to give it a workout to get all the pixels working properly again and then it'll be just fine. I adjusted the contrast between full dark and nothing multiple times and turned the calculator on and off after each cycle and now it works like new.

Yes it does. It can do 1-var and 2-Var statistics.

Enter the angle in degrees-minutes-seconds using the single-tick (') for all three parts. Do NOT use the degree and second symbols. In my TI-86 manual, it's on page 285.

maybe try changing the small memory battery inside, I think its a cr1616 or cr1620. If this doesn't work use it as a paperweight.
