4. Suppose the average height of American adult males is 5 feet 10 inches (70 inches) and the standard deviation is 3 inches. If I randomly sample 100 men: A) What will the expected value of the average height of that sample be? (i.e. the mean of the sampling distribution) B) What will the standard deviation of the average height in that sample be? (i.e. the standard deviation of the sampling distribution) C) How big of a sample would we need to have a standard deviation of 0.1 inches?
