Answer:
B.
Step-by-step explanation:
In hypothesis testing if we don't reject the null hypothesis then it doesn't mean that we are accepting the null hypothesis. It simply means that we have insufficient evidence of rejection of the null hypothesis. This means that we have insufficient evidence to claim that our alternative hypothesis is true.
Hence, if we do not reject the null hypothesis, we conclude that there is not enough statistical evidence to infer that the alternative hypothesis true.
