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?

4. According to flightstats.com, American Airline flights from Dallas to Chicago are on time 80% of the time. Suppose 100 flights are randomly selected. a) Explain why this is a binomial experiment. b) Compute the mean and standard deviation of the random variable X, the number of on- time flights in 100 trials of the probability experiment. c) Would it be unusual to observe 75 on-time flights in a random sample of 100 flights from Dallas to Chicago? Why?

A certain flight arrives on time 80 percent of the time. Suppose 174 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 148 flights are on time. (b) at least 148 flights are on time. (c) fewer than 133 flights are on time. (d) between 133 and 150, inclusive are on time.
Suppose flight AA380 (from NYC to Chicago) arrives on time 87% of the time. Suppose 120 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that: a) at least 90 flights are on time. b) fewer than 106 flights are on time. (d) between 106 and 113, inclusive are on time
