Based on long experience, an airline found that about of the people making reservations on a flight from Miami to Denver do not show up for the flight. Suppose the airline overbooks this flight by selling 267 ticket reservations for an airplane with only 255 seats. (a) What is the probability that a person holding a reservation will show up for the flight? (b) Let n. 267 represent the number of ticket reservations. Let rrepresent the number of people with...

2. Because many passengers who make reservations do not show up, airlines often overbook flights (sell more tickets than there are seats). A Boeing 767-400ER holds 245 passengers. The airline believes the rate of passenger not showing up is 5% and sells 255 tickets. [10 Marks] a. Use Normal approximation to determine the binomial probability of at least 246 passengers showing up. [9 Marks] b. Should the airline change the number of tickets it sells for...

USA Today reported that about 20% of all people in the United States are illiterate. Suppose you take seven people at random off a city street. (a) Make a histogram showing the probability distribution of the number of illiterate people out of the seven people in the sample (b) Find the mean and standard deviation of this probability distribution. (Round your answers to two decimal places.) μ = people σ = people Find the expected number of people in this sample who...

3 Question Help Because many passengers who make reservations do not show up, airlines often overbook flights (sell more tickets than there are seats). A certain airplane holds 292 passengers. If the airline believes the rate of passenger no-shows is 6% and sells 308 tickets, is it likely they will not have enough seats and someone will get bumped? a) Use the normal model to approximate the binomial to determine the probability of at least 293 passengers showing up. b)...

Consumer Reports rated airlines and found that 72% of the flights involved in the study arrived on time (le, within 15 minutes of scheduled arrival time). Assuming that the on-time arrival rate is representative of the entire commercial airline industry, consider a random sample of 186 flights. (Round your answers to two decimal places.) What is the expected number that will arrive on time? 133.82 What is the standard deviation of this distribution? 5.4 Need Help? Read

Because many passengers who make reservations do not show up, airlines often overbook flights (sell more tickets than there are seats). A certain airplane holds 154 passengers. If the airline believes the rate of passenger no-shows is 7% and sells 166 tickets, is it likely they will not have enough seats and someone will get bumped? a) Use the normal model to approximate the binomial to determine the probability of at least 155 passengers showing up. b) Should the airline...

A small hotel has 10 rooms. From past experience, they know that
20% of the time people who make reservations do not show up, so as
a result, they overbook by accepting 12 reservations for a given
night. Let X be the number of no shows that night(people who don’t
show up).
