An airline claims that the no-show rate for passengers is 5%. In a sample of 420 randomly selected reservations, 19 were no-shows. At α = 0.05, test the airline’s claim. Also construct a 95% confidence interval for the proportions of no-show in the airline reservations to see the connection between confidence interval and hypothesis testing.

An airline claims that the no-show rate for passengers is less than 5%. In a sample of 420 randomly selected reservations, the rate of no-show is 4.5%. Set up the null and alternative hypothesis to test this claim. Describe what type 1 error and type 2 error are in this case. Find the test statistic and make a decision at 5% level of significance.

Because not all airline passengers show up for their reserved seat, an airline sells 125 tickets for a flight that holds only 124 passengers. The probability that a passenger does not show up is 0.10, and the passengers behave independently. Round your answers to two decimal places (e.g. 98.76). (a) What is the probability that every passenger who shows up gets a seat? (b) What is the probability that the flight departs with empty seats? (c) What are the mean...

An airline estimates that 80% of passengers who reserve the tickets actually show up for the flights. Based on this information, it has to decide how many tickets it will sell for each flight, which is typically more than the number of seats actually available. In the economy section of a particular aircraft, 200 seats are available. The airline sells 225 seats. What is the probability that more passengers will show up than there are seats for?
