The documentation for both function states that (about lines 44-45)

If @var{h} is 0 the null hypothesis is accepted, if it is 1 the null hypothesis is rejected.

But this is incorrect, the null hypothesis is never accepted. It would be factually correct to instead state

If @var{h} is 1 the null hypothesis is rejected, if is 1 the null hypothesis can not be accepted.

Which has a completely different meaning (we can never accept the null hypothesis). It is possible other stat related function also make that mistake, I did not check all of them out.
