Airfares were based on the totalticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. Assume domestic airfares arenormally distributed with a standard deviation of $110. Use Table 1 in Appendix B.What is the probability that a domestic airfare is $560 or more (to 4 decimals)?What is the probability that a domestic airfare is $260 or less (to 4 decimals)?What if the probability that a domestic airfare is between $300 and $500 (to 4 decimals)?I What is the cost for the 3% highest domestic airfares?
