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.
