So, by selection bias, you are saying that even though the acceptance rate for math majors is higher it is due to the lesser number of applicants? Also, would the numbers you provided be annual? I was thinking of majoring in math or a science major (bio [ though I wouldn’t do bio now after this information], chem or biochem). Besides from applying to med school, wouldn’t it look a bit funny to a hospital if you wanted to be a doctor but majored in math or do they not care about your major too much?
