Question

What effect does airline consolidation have on passengers?

Answer #1

In the first nine months of a year, airline consumer complaints
were
0.91 per 100,000 passengers..
What is the probability that in the next 100,000 passengers, the
airline will have at least two complaints?
The probability that the airline will have at least two
complaints is ( ).
(Round to four decimal places as needed.)

An airline, believing that 4% of passengers fail to
show up for flights, overbooks. Suppose a plane will
hold 300 passengers, and the airline sells 310 tickets. What is the
probability the airline will not have enough seats, so someone gets
bumped? Round your answer to 3 decimal
places.

An airline needs an estimate of the average number of passengers
(the mean passenger load) on a newly scheduled flight. If the mean
passenger load on this flight does not exceed 120 passengers in the
first few months of operation, the airline plans to discontinue the
flight. Its experience is that data for the first month of flights
are unreliable, but thereafter the passenger load settles down.
Therefore, the sample mean passenger load is calculated for the
first 20 weekdays...

Phoenix is a hub for a large airline. Suppose that on a
particular day, 8000 passengers arrived in Phoenix on this airline.
Phoenix was the final destination for 1200 of these passengers. The
others were all connecting to flights to other cities. On this
particular day, several inbound flights were late, and 430
connecting passengers missed their connecting flight and were
delayed in Phoenix. Of the 430 who were delayed, 65 were delayed
overnight and had to spend the night...

The baggage weights for passengers using a domestic airline are
normally distributed with a mean of 22 lbs. and a standard
deviation of 4 lbs.
(a) If a passenger is selected at random, what is the
probability that the baggage weight of that passenger is more than
30 lbs?
(b) Suppose the limit on total luggage weight is 2250 lbs. If
100 passengers are aboard the airline, what is the probability that
their total baggage weight exceeds the limit?
Show...

Overweight baggage. Suppose weights of the
checked baggage of airline passengers follow a nearly normal
distribution with mean 38 pounds and standard deviation 5.4 pounds.
Most airlines charge a fee for baggage that weigh in excess of 50
pounds. Determine what percent of airline passengers incur this
fee. Round your answer to four decimal places

What is the law of effect? What effect does it have on
behavior?

The airline knows that in the long run, only 90% of passengers
who book a seat show up for their flight. On a flight with 300
seats, there are 324 reservations. (a) Assuming passengers make
independent decisions what is the chance that the flight will be
overbooked? (b) Redo (i) assuming passengers travel in pairs and
each pair flips a coin with probability 0.9 of heads to see if they
will both show up or both stay home.
Explain your...

On a particular airline, 65% of all
passengers accept a bag of peanuts during their flight. The
airplanes for this airline have 180 seats, and all seats are always
sold out. (Use this for #3 – 5).
5. Would bringing 126 bags of
peanuts be sufficient on each flight? Calculate the probability
that they would run out of peanuts on a randomly chosen flight,
making sure to sketch, label, and shade the Standard Normal
Distribution appropriately.

An airline claims that the no-show rate for passengers is less
than 10%. In a sample of 420 randomly selected reservations, 19
were no-shows. A α = 0.05, test the airline's claim.
