4. American Airlines flights from Dallas to Chicago are on time 80% of the time. Suppose 15 flights are randomly selected, and the number of on-time flights is recorded.
a. Is this a binomial experiment? Explain.
b. Find the probability that exactly 10 flights are on time.
c. Find the probability that fewer than 10 flights are on time.
d. Find the probability that at least 10 flights are on time.
e. Find the mean and the standard deviation of flights that are on time. If 13 flights are on time, would that be significant?
