Question

In a randomized, controlled trial, there was found to be statistically significant evidence of a reduction in myocardial infarction (heart attack) risk in participants who took aspirin. Participants who took aspirin had a 44% reduction in risk of heart attack as compared to their counterparts who received placebo (relative risk = 0.56; 95% confidence interval, 0.45 to 0.70). If you conducted a hypothesis test on the data, do you expect the p-value to be less than 0.05 or greater than 0.05? Explain.

Explanation / Answer

Since the null hypothesis is rejected, it is clear that P-value should be less than 0.05.
