Consumer Reports rated airlines and found that 89% of the flights involved in the study arrived on time (i.e., within 15 minutes of scheduled arrival time). Assuming that the on-time arrival rate is representative of the entire commercial airline industry, consider a random sample of 205 flights. (Round your answers to two decimal places.) What is the expected number that will arrive on time? What is the standard deviation of this distribution?
