According to flightstats.com, American Airlines flights from Dallas to Chicago are on time 80% of the time. Suppose 17 flights are randomly selected, and the number of on-time flights is recorded. (a) Explain why this is a binomial experiment. (b) Determine the values of n and p. (c) Find and interpret the probability that exactly 11 flights are on time. (d) Find and interpret the probability that fewer than 11 flights are on time. (e) Find and interpret the probability that at least 11 flights are on time. (f) Find and interpret the probability that between 9 and 11 flights, inclusive, are on time. (a) Identify the statements that explain why this is a binomial experiment. Select all that apply. A. The probability of success is the same for each trial of the experiment. B. The experiment is performed a fixed number of times. C. There are three mutually exclusive possible outcomes, arriving on-time, arriving early, and arriving late. D. There are two mutually exclusive outcomes, success or failure. E. Each trial depends on the previous trial. F. The experiment is performed until a desired number of successes are reached. G. The trials are independent. H. The probability of success is different for each trial of the experiment. (b) Using the binomial distribution, determine the values of n and p. n = 17 (Type an integer or a decimal. Do not round.) p = 0.80 (Type an integer or a decimal. Do not round.) (c) Using the binomial distribution, the probability that exactly 11 flights are on time is (Round to four decimal places as needed.)
