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( 68 2.3 or or b. Find the probability that the person is between 66 and 69.5 inches. c. The middle 20% of Martian heights lie between what two numbers? Low: inches High: inches
