Based on long experience, an airline found that about 8% 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 263 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 = 263 represent the number of ticket reservations. Let r represent the number...

State Farm Insurance studies show that in Colorado, 45% of the
auto insurance claims submitted for property damage were submitted
by males under 25 years of age. Suppose 12 property damage claims
involving automobiles are selected at random.
(a) Let r be the number of claims made by males under
age 25. Make a histogram for the r-distribution
probabilities.
(b) What is the probability that three or more claims are made by
males under age 25? (Use 3 decimal places.)...

please answer these questions
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...

Because not all airline passengers show up for their reserved seat, an airline sells 129 tickets for a flight that holds only 123 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...

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...

Have you ever tried to get out of jury duty? About 25% of those called will find an excuse (work, poor health, travel out of town, etc.) to avoid jury duty†. If 11 people are called for jury duty, find the following. (a) What is the probability that all 11 will be available to serve on the jury? (Round your answer to three decimal places.) (b) What is the probability that 5 or more will not be available to serve...
