Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

goodluck!

I want to do a chi-square test on the TI-85

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.

Ti-84 BINOMIAL PDF

I encountered this same problem with the TI-84. Turns out you have to put your P (Percentage) as out of one hundred. For example. With my problem I had;

Trails: 13
P: 53/100
X Value: L1 (List 1)

And then it posted my probabilities to the L2 list. For some reason if you just put 53, or whatever your percentage of success in, it won't calculate.

My ti-84 calculator wont react to anything and it says garbage collecting. i think the bar on the side should move and its not moving and its been like this for several weeks. i did download a whole pile...

I remember this happening once to my TI-83. I know it's a different calculator. But it happened frequently. Without completely reconfiguring the calculator, you can remove the batteries whenever you see the message and when you start it up again, it should be okay. It may continue to display this message once in a while. I used to just remove the batteries. I don't know if it will work on your TI-84 the way it worked on my TI-83, but I hope this helped!
