If a study is statistically significant with P value 0.05, all is True except for (in other words, select the "wrong* statement) The 95% confidence interval should not include the null value OB. Both P value and confidence interval should imply statistical significance OC. We reject the null in favor of the alternative O D. The study is also clinically significant

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...
