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, p, 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 of the sampling distribution of ?̂?

μp^=

What is the standard deviation of the sampling distribution of ?̂? Give your answer precise to three decimal places.

σp^=

A carnival game involves a spinner that is designed so that in 20 percent of spins the player will win a prize. A random sample of 100 spins will be observed and the random variable X = number of times in the sample that the player won a price will be recorded. For the questions below, consider the process of finding the indicated probability by using the normal distribution as an approximation, including making the appropriate continuity correction. (Note that...
