In addition, the airline charges for making a reservation on its website, checking bags, and inflight beverages. These additional charges average $39 per passenger.+ Suppose a random sample of 57 passengers is taken to determine the total cost of their flight on Allegiant Airlines. The population standard deviation of total flight cost is known to be $40. (a) What is the population mean cost per flight in dollars? (b) What is the probability the sample mean will be within $10 of the population mean cost per flight? (Round your answer to four decimal places.)
