2.4-9. Suppose that the percentage of American drivers who multitask (e.g., talk on cell phones, eat a snack, or text at the same time they are driving) is approximately 80%. In a random sample of n = 20 drivers, let X equal the number of multitaskers. a. How is X distributed? b. Give the values of the mean, variance, and standard deviation of X. c. Find (i) P(X= 15), (ii) P(X > 15), and (iii) P(X ≤ 15).
