There's 2 scientific papers. These papers described two different randomized control double-blind experiments, each of which was testing the same new drug to see whether it lowers cholesterol in patients with high cholesterol. Both papers used the same significance level 0.05. One of the papers calculated a p-value less than a and concluded that the new drug is effective, while the other paper calculated a p-value greater than a and could not conclude that the new drug is effective. Write two possible reasons (other than fraud or a computational mistake) for the difference in conclusions between the two papers.
