Phoenix is a hub for a large airline. Suppose that on a particular day, 8,000 passengers arrived in Phoenix on this airline. Phoenix was the final destination for 1,400 of these passengers. The others were all connecting to flights to other cities. On this particular day, several inbound flights were late, and 420 passengers missed their connecting flight. Of the 420, 85 were delayed overnight and had to spend the night in Phoenix. Consider the chance experiment of choosing a passenger at random from these 8,000 passengers. (Round your answers to three decimal places.)

(a)

Calculate the probability that the selected passenger had Phoenix as a final destination.

(b)

Calculate the probability that the selected passenger did not have Phoenix as a final destination.

(c)

Calculate the probability that the selected passenger was connecting and missed the connecting flight.

(d)

Calculate the probability that the selected passenger was a connecting passenger and did not miss the connecting flight.

(e)

Calculate the probability that the selected passenger either had Phoenix as a final destination or was delayed overnight in Phoenix.

(f)

An independent customer satisfaction survey is planned. Fifty passengers selected at random from the 8,000 passengers who arrived in Phoenix on the day described above will be contacted for the survey. The airline knows that the survey results will not be favorable if too many people who were delayed overnight are included. Write a few sentences explaining whether or not you think the airline should be worried, using relevant probabilities to support your answer.

The airline ---Select--- should should not be worried because the probability someone was delayed overnight is .

A regional airline transfers passengers from small airports to a larger regional hub airport. The airline data analyst was assigned to estimate the revenue ( in thousands of dollars) generated by each of the 22 small airports based on two variables: the distance from each airport ( in miles) to the hub and the population ( in hundreds) of the cities in which each of the 22 airports is located. The data is given in the following table. Airport revenue ...

The Airline Passenger Association studied the relationship between the number of passengers on a particular flight and the cost of the flight. It seems logical that more passengers on the flight will result in more weight and more luggage, which in turn will result in higher fuel costs. For a sample of 20 flights, the correlation between the number of passengers and total fuel cost was 0.688. State the decision rule for 0.025 significance level: H0: ρ ≤ 0; H1:...

Since 911, heightened airline security has increased frustrations for both airline employees and passengers. Passengers have to abide by the ever more rules that airline employees must enforce. For instance, on a flight from Europe to the United States, a simple passenger request escalated quickly. “John Murphy asked a flight attendant about a sign telling passengers not to venture beyond the curtain separating the economy class from the rest of the plane.”, the New York Times reported. “He wanted to...

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).
