According to a study done by UCB students, the height for Martian adult males is normally distributed with an average of 65 inches and a standard deviation of 2.4 inches. Suppose one Martian adult male is randomly chosen. Let X = height of the individual. Round all answers to 4 decimal places where possible. a. What is the distribution of X? X ~ N(,) b. Find the probability that the person is between 66.8 and 67.8 inches.  c. The middle 50% of Martian heights lie between what two numbers? Low:      inches High:     inches
