Assume you are managing an airport and want to improve passenger flow by studying check-in times. You observe that passengers arriving early for check-in have consistent processing times, while those arriving closer to departure face variability. After closely studying the collected data, you observe the following:
a. Passengers who arrive within the scheduled check-in period (2 hours before departure) experience uniformly distributed check-in times between 5 and 15 minutes.
b. For late arrivals, the time it takes for passengers to pass through security and reach the boarding gate follows an exponential distribution with a mean of 10 minutes.
Using this context, we will address learning objectives and topics related to continuous probability density functions, uniform distribution, and exponential distribution.
Explain what a continuous probability density function is and how it differs from a discrete probability distribution. Use the check-in time data from the airport in your explanation.
What is the probability that a passenger's check-in time is between 7 and 10 minutes, assuming the check-in times are uniformly distributed between 5 and 15 minutes? Provide your solution using appropriate formulas and notations.
What is the probability that a late-arriving passenger will pass through security and reach the gate in less than 5 minutes, assuming an exponential distribution with a mean of 10 minutes? Provide your solution using appropriate formulas and notations.
