Question about Casio Office Equipment & Supplies
(991ES-Plus) every time i am on stat mode, in A+bx, i enter the Xs and the Ys, when i want to get the X-hat or the Y-hat (the ones with the caret ^ ) i get syntax error
You can not get directly x^ or y^ directly ,,,,, just enter a number before x^,,,, just like 1x^

Just in case : Press [SHIFT][CLR] (9) [3: ALL] to reset the calculator and try [MODE] again.
If that does not work, your calculator may be defective or a fake (not the genuine article). If at all possible, return it to where you bought it and get a refund.
Here is a picture of the FX-115ES, its face looks like the 991ES. Hope I am mistaken.

Not knowing what kind of probability calculations you want to perform, I can only show you how to access the distributions that this calculator has to offer.
After you enter your data and do the usual statistics, you press SHIFT STAT and select 7:Distr. You get acces to
4: X to t, the variate.
See the exemples in the Appendix to the user's manual, in particular #059.
Hope it helps.
