An opinion poll asks an SRS of 501 teenagers, "Generally speaking, do you approve or disapprove of legal gambling or betting?" Suppose that, in fact, exactly 50% of all teenagers would say Approve if asked. (This is close to what polls show to be true.) The poll's statisticians tell us that the sample proportion who say Approve will vary in repeated samples according to a Normal distribution with mean 0.5 and standard deviation about 0.022. Using the 68-95-99.7 rule, what is the probability that fewer than 54.4% (Use decimal notation. Give your answer as an exact proportion.) probability: say Yes?
