A population of values has a distribution with u - 56 and o - 89.4. You intend to draw a random sample of size n = 84. According to the Central Limit Theorem: (a) What is the mean of the distribution of sample means? HE = (b) What is the standard deviation of the distribution of sample means? (Report answer accurate to 2 decimal places.) (c) In a random sample of n=84, what is the probability that its sample mean is more than 46.9? Round to three decimal places. (d) In a random sample of n=84, what is the probability that its sample mean is less than 52.3? Give your answer to three decimal places
