Suppose that, as part of a game at a charity carnival, players are invited to spin a wheel for a chance at winning either a small, medium, or large prize. The wheel is constructed so that the probability that a player does not win a prize, ?p, is 0.50. If a random sample of 40 players is selected, then ?̂ p^ is the proportion of players in the sample who do not win a prize. What is the mean of the sampling distribution of ?̂ p^? ??̂ μp^=     What is the standard deviation of the sampling distribution of ?̂ p^? Give your answer precise to three decimal places. ??̂ σp^=
