Allegiant Airlines charges a mean base fare of $89. In addition, the airline charges for making a reservation on its website, checking bags, and inflight beverages. These additional charges average $35 per passenger. Suppose a random sample of 50 passengers is taken to determine the total cost of their fight on Allegiant Airlines. The population standard deviation of total flight cost is known to be $39. Use-table. a. What is the population mean cost per flight? 4 b. What is the probability the sample mean will be within $10 of the population mean cost per fight (to 4 decimals)? c. What is the probability the sample mean will be within $5 of the population mean cost per flight (to 4 decimals)?
