Question: Suppose that if a presidential election were held today, 53% of all voters would vote for Obama over McCain. (You can substitute the names of the current presidential candidates.)

b. If 6000 voters are sampled randomly, what is the probability that the sample will indicate (correctly) that Obama is preferred to McCain?
