Bus is a mode of public transportation that is designed to carry a larger number of passengers than cars or vans. Assuming there is a bus stop denoted as S, the number of passengers arriving at S can be described by a normal distribution every minute (mean = 25, standard deviation = 6).
By reducing the amount of time that passengers are required to wait, their overall satisfaction can be improved. Research indicates that if the waiting time exceeds 15 minutes, passengers are likely to experience feelings of unhappiness.
Now, your task is to propose a solution (e.g. how many minutes a bus should arrive at S) to ensure only less than 5% of all passengers feel unhappy.
Assumptions:
Bus maximum capacity: 40 passengers. First come, first served. One route and one stop only.
Please use “Link” to represent if passengers get on/off the bus. You can add any reasonable assumptions.
