## Pivot table for ChiSquaretest?...

Maple

Hi I have an n×4 matrix of answer data to a questionnaire I would like to convert into a pivot table. So I can do a Chi2test.

How do I construct said table?

Maple

I have been trying to to get a loop to sum the elements of a list of n size, and then take a certain element of summen list (which meets) a certain condition. And then print it out.

What I can get it to do is printing the input list, and summing the elements in a new sister list sequence. And then if I for instance want its to print the element in testseq which is less than 15. Then it instead prints all elements less than 15 in testseq. What I would like to do is to move the index, so it only prints 10 and save it to a constant?

So what am I missing?

test := [1, 2, 3, 4, 5, 6, 7, 10];
test := [1, 2, 3, 4, 5, 6, 7, 10]

testseq := [seq(sum(test[i], i = 1 .. j), j = 1 .. numelems(test))];
testseq := [1, 3, 6, 10, 15, 21, 28, 38]

for i to nops(test) while testseq[i] < 15 do
testseq[i];
end do;

Maple 2023

Since I began to use Maple for teaching back in 2014 (now on 2023 version), the following happens to some students.

While they are in math mode, the Maple engine suddenly stops being unable to do anything (even 2+2). Only way to solve this is to start a new document or restart Maple. I have seen this issue on both Mac and PC version.

So my question is what causes this?

Maple 2022

I teach high school math where we use Maple. Some times some students who use Maple 2022 on Mac computers both older and new version of the OS, experience that the document won't react to simple things like plot, solve of loading packages with the "with" command.

Any idea could be causing this? Because the error goes away if we load a new document within Maple or restart the program.

## Interval of normal distribution?...

Maple

Dear friends,

If you import a table of 1-dimensional data assuming it normally distributed. Any command in Maple to generate the interval of normal distribution?
