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 wins a small prize, ?, is 0.40. If a random sample of 40 players is selected, then ?̂ is the proportion of players in the sample who win a small prize. What is the mean and standard deviation of the sampling distribution of ?̂? Give your answer to three decimal places.
