Explanation / Answer

The first of these is the null hypothesis, which is the hypothesis of no difference.

The alternative hypothesis is constructed such that it is opposite to null hypothesis.

If the null hypothesis is rejected then we are correct to say that we accept the alternative hypothesis.

However if the null hypothesis is not rejected, then we do not say that we accept the null hypothesis.

Please note that we are attempting to provide enough evidence for alternative hypothesis.

We are not trying to prove that the null hypothesis is true.

As a result of our test the significance does not give any evidence for truth of null hypothesis
