An advertising agency claims that 75% of all doctors recommend aspirin over any other pain reliever. If this claim is indeed valid, what is the approximate probability that in a sample of 96 doctors who were interviewed at random and who respond independently less than 60 will recommend aspirin? If in such a survey you actually found out that 58 out of 96 preferred aspirin, what would you think about the genuine nature of the claim? (The first question I already know, but the second I am having trouble with, please help!)

75/100 = 56/96?

Well, obviously it would be a biased claim.

I would think that one or both of the surveys were wrong or improperly biased.
