A certain flight arrives on time 82 percent of the time. Suppose 198flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 172 flights are on time. (b) at least 172 flights are on time. (c) fewer than148 flights are on time. (d) between 148 and 168, inclusive are on time.
