Your flight has been delayed: At Denver International Airport, 84% of recent flights have arrived on time. A sample of 14 flights is studied. Round the probabilities to four decimal places.
(a) Find the probability that all
14 of the flights were on time
(b) Find the probability that exactly
12 of the flights were on time.
(c) Find the probability that
12 or more of the flights were on time.
(d) Would it be unusual for
13 or more of the flights to be on time?
It would/would not be unusual for 13 or more flights to be on time since the probability is ________

About 24% of flights departing from New York's John F. Kennedy International Airport were delayed in 2009. Assuming that the chance of a flight being delayed has stayed constant at 24%, we are interested in finding the probability of 10 out of the next 100 departing flights being delayed. Noting that if one flight is delayed, the next flight is more likely to be delayed, which of the following statements is correct? .
(A) We can use the geometric distribution...

You are a frequent flyer and you have been wondering whether the
number of flights delayed is influenced by how busy the airport is
that you are flying into. You have collected data for the number of
delayed flights and the total number of flights on the airport at
your hometown on 20 consecutive days and the data are presented
below:

Flights American Airlines Flight 201 from New York's JFK airport
to LAX airport in Los Angeles uses a Boeing 767-200 with 168 seats
available for passengers. Because some people with reservations
don't show up, American can overbook by accepting more than 168
reservations. If the flight is not overbooked, the airline will
lose revenue due to empty seats, but if too many seats are sold and
some passengers are denied seats, the airline loses money from the
compensation that must...

A medium-sized airport has a limited number of international
flights that arrive and require immigration and customs. The
airport would like to examine the customs staffing and establish a
policy on the number of passengers who should have bags searched
and the staffing of the customs facility. The number of passengers
who arrive on these large planes is uniformly distributed between
240 and 350, and the simulation is to run until all passengers on
the plane have been completely processed...

A certain flight arrives on time 84 percent of the time. Suppose
167 flights are randomly selected. Use the normal approximation to
the binomial to approximate the probability that
(a) exactly 127 flights are on time.
(b) at least 127 flights are on time.
(c) fewer than 144 flights are on time.
(d) between 144 and 154, inclusive are on time.

You have been asked to conduct research on behalf of the
Adelaide Airport. Adelaide Airport has recently undergone a
renovation and wants to determine the most appropriate retail
outlets to have on its premises. With the current situation with
COVID-19, they need to understand how this has changed people’s
intended shopping and eating behaviour at airports, and what impact
this will have on their retail outlets.

Passengers arriving into Pearson International Airport are to
have their temperature check before leaving the airport. Any
passengers with a fever are required to go into quarantine. Three
Nurses perform the check. An average of 3.84 passengers per minute
arrive at the checkpoint and wait in a single line. They are
checked by the first available nurse. It takes on average 25
seconds to check a passenger. Assume that inter-arrival times and
service times are exponential distribute, FCFS, infinite queue,...

Regis International Corporation (RIC), a Denver based technology
company, has been applying its expertise in microprocessor
technology to develop a small computer specifically designed to
control home appliances. Once programmed, the computer would
automatically control the heating and air-conditioning system, hot
water heater, and even small appliances such as coffee makers. By
increasing the energy efficiency of a home, the appliance control
computer can save on costs hence pay for itself in a few years.
This effort has now reached...
