In scientific research, which action is described as part of the process?

• A. Accept the hypothesis
• B. Reject the null hypothesis
• C. Reject the hypothesis
• D. Accept the null hypothesis

Answer: (B)

In hypothesis testing, the researcher uses evidence from the data to decide whether the null hypothesis should be rejected. If the data show a result unlikely under the null (often judged by a low p-value at a chosen significance level), the standard action is to reject the null hypothesis in favor of the alternative. This reflects the idea that the observed effect is not easily explained by chance alone. It's not typical to say we "accept" the null, because no result proves no effect; we simply fail to reject it when evidence isn't strong enough. Similarly, saying we "reject the hypothesis" without specifying that it’s the null can blur which statement is being challenged; the established practice is to reject the null. Therefore, the action described as part of the process is to reject the null hypothesis.
