A researcher is testing whether a new drug reduces blood pressure more than a placebo. The study is designed with 80% power to detect a clinically meaningful difference of 10 mmHg, using α = 0.05. After the study, the researcher finds a p-value of 0.12 and concludes there is no significant difference. However, the observed difference was 8 mmHg favoring the new drug. What is the most accurate interpretation of this result?
