Suppose that the mean cost of domestic airfares in Canada is $300 per ticket. Also assume that airfares are normally distributed with a standard deviation of $100. • What is the probability that a domestic flight costs at most $508? (Enter a decimal in [0, 1] correct to four decimal places.) • What is the probability that the price of a domestic flight is between $100 and $200? (Enter a decimal in 0, 1 correct to four decimal places.) • What is the minimum cost of the 6.3% most expensive domestic tickets? (Enter an exact dollar amount without cents or units.)
