The mean cost of domestic airfares in the United States rose to an all-time high of $450 per ticket (Bureau of Transportation Statistics website, November , ). Airfares were based on the total ticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. Assume domestic airfares are normally distributed with a standard deviation of $100 What is the probability that a domestic airfare is $580 or more (to 4 decimals)? What is the probability that a domestic airfare is $400 or less (to 4 decimals)?
