Yes, the null Hypotheses cannot be stated
TRUE or UNTRUE.
But it must be completely get that we are never
searching that: THIS IS NOT the aim of the NHST . . .
What we want to know if there is sufficient
evidence that the Null Hypothesis is unlike given
data and confidence level (usually 95%).
Situation leading to reject H0.
If there is not sufficient evidence we
must NOT MAKE ANY STATEMENT about
the null - we failed to disprove - the ONLY thing we
are allowed to conclude.
How we can say that the null is accepted if we have any
information about the difference between the null and
the value of the test statistic we calculated? How???
It was R. Fisher established one century ago.
