You have a coin that is not weighted evenly and therefore is not a fair coin. Assume the true probability of getting tails when the coin is flipped is 0.55. Find ua, on and o. for all possible samples of 66 flips of the coin. What is the average sample proportion for the population consisting of all such possible sample proportions? What is the standard deviation of the population consisting of all such possible sample proportions? What is the variance of the population consisting of all such possible sample proportions?
