#22. In Exercise 17, it was reported that about 1% of all airline flights scheduled to depart from US airports are canceled. You select 100 flights at random. Assuming all the binomial conditions are met, compute the a. expected number of canceled flights. Explain the meaning of the expected value in this situation. b. variance of the random variable "number of can- celed flights." c. standard deviation of the random variable "num- ber of canceled flights."

Exercise 17: In a given year, approximately 1% of all flights sched- uled to depart from US airports are canceled (source: Department of Transportation Statistics, Intermodal Data Base). You select 10 flights at random. Use the binomial probability function to compute the proba- bility that a. none of the flights will be canceled. b. exactly one of the flights will be canceled. c. no more than one of the flights will be canceled
