In a clinical trial for patients with hangnails, the test group soaked their hands in warm water and were given an experimental drug. They showed statistically significant improvement
(p-value < 0.03)
as compared to the control group, which did nothing to treat their hangnails. The president of the drug company sponsoring this trial asserted that this p-value shows that the new drug had a 97% probability of helping hangnails. Discuss the validity of the president's comment.
A) It is likely that there is a strong selection bias in the results.
B) Both the groups, the test group and the control group, should have had their hands soaked in warm water.
C) Researchers should know which group was controlled and which group was the study group to prevent further bias.
D) The study should be double-blind to prevent further bias.
I think the answer is A. I'm I correct?
