An article reported that what airline passengers like to do most on long flights is rest or sleep; in a survey of 3697 passengers, almost 80% did so. suppose that for a particular route the actual percentage is exactly 80%, and consider randomly selecting nine passengers. then x, the number among the selected nine who rested or slept, is a binomial random variable with n = 9 and p = 0.8. (round your answers to four decimal places.)
