Give your answer precise to three decimal places. ??̂ = Which of the following graphs shows the sampling distribution of ?̂ ? A histogram shows an approximately symmetric sampling distribution centered at 16 with a standard deviation of 3.098. A histogram shows an approximately symmetric sampling distribution centered at 0.40 with a standard deviation of 0.077 A histogram shows an approximately symmetric sampling distribution centered at 0.16 with a standard deviation of 0.058. A histogram shows a left-skewed sampling distribution centered at 0.40 with a standard deviation of 0.047. A histogram shows an approximately symmetric sampling distribution centered at 0.40 with a standard deviation of 0.110.
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.
