Correct answer: B
The correct answer is (b) It is only the null hypothesis that can be tested. The scientific method of statistical testing is designed to assess the evidence against the null hypothesis. We can either reject the null hypothesis (lending support to the alternative) or fail to reject it; we never directly "test" or "prove" the alternative hypothesis.
