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, infinite population size.

(a) What is the probability that a passenger will not have to wait when they arrive at the checkpoint? (6 marks)

(b) On average, how many passengers will be at the checkpoint (waiting & being scanned)? (4 marks)

(c) When the passenger finally reaches the checkpoint, what is the probability it will take 20 seconds or less to check their temperature?

(d) What is the probability there will be more than 2 passengers arriving to the checkpoint in a one min time period.

All airport passengers at the Capital City Airport must pass through a security screening area before proceeding to the boarding area. The airport has three screening stations available, and the facility managers must decide how many to open at any particular time. The average time for processing one passenger at each screening station is 0.5 minutes. On Saturday morning the arrival rate is 3.3 passengers per minute. Assume that processing times at each screening station follow an exponential distribution and...

A random sample of 19 airline passengers at Hartsfield Jackson International airport showed that the mean time spent waiting in line to pass though the TSA checkpoint was 31 minutes with a standard deviation of 7 minutes. Construct a 95 % confidence interval for the mean waiting time by all passengers in the TSA checkpoint at this airport. Assume that such waiting time for all passengers is normally distributed. A) 31+1.65(7/P19) B) 31+1.746(7/P19) C) 31+1.96(7/P19) D ) 31+2.101(7/P19)
