Hi Experts,

This problem really drives me insane. I'm using my recently bought casio Algebra FX 2.0 Plus calculator to calculate chi square, there are Observed/Expected value needed to be filled in which requires to be in matrix form. Anybody knows how to fill in those data in matrix form using this calculator? I did change the dimension from 3x3 , 4x4 , etc. I've tried hundred times, it always gives me dimension errors and wrong answers.

Below is my data :

observed N expected N
31---------------------------- 27
19---------------------------- 27
19 ----------------------------27
25---------------------------- 27
41---------------------------- 27



This is the correct answer : (chi square) x^2 = 12.740, df = 4 , asymp sig = .000
I repeatedly fail to prove this answer using this calculator, The explanation on the manual book is very unclear.
Thanks.
