significant Shapiro-Wilk Test [General Statistics]
Hi Helmut,
The absence of a low p-value is not proof of the null being right. We can't prove which distribution the data follows but we can, so to say, test with some degree of power and with some alpha which distribution it doesn't follow.
What I am trying to say is I don't think it is contradictory to have two unrejected mutually exclusive null hypotheses.



❝ If you run two concurrent tests (one against the normal and the other one against the log-normal) you may end up with two nonsignificant results (as in slide 6) – which is contradictory.
