I will rate accordingly with multiple votes.In the process of using the scientific method, a researcher: O Directly tests both the null and alternative hypotheses. O Directly tests only the alternative hypothesis because this is the hypothesis of interest. O Directly tests only the null hypothesis because this is the hypothesis of interest. O Directly tests only the null hypothesis because the null hypothesis leads to a specific prediction that can be compared with data. O Can not directly test either hypothesis.
