A study finds that a new drug lowers systolic blood pressure by 2 mmHg with a p-value of < 0.001. While the result is statistically significant, the physician questions whether it will make a real difference in patient outcomes. What does this scenario illustrate about clinical significance?

A researcher is analyzing blood pressure data from two different studies. Study A has a sample size of 25 participants, while Study B has 250 participants. Assuming similar variability in both groups, how would the standard error of the mean (SEM) in Study B likely compare to Study A, and why?
