A queuing theory analysis for bank teller windows comes up with a value of 0.10 for P, indicating that customers are likely to wait about 10 minutes for each transaction.

Question

Quizplus · Accepted Answer

The given statement is incorrect.

P (probability of waiting) in queuing theory represents the percentage of time that the server (e.g. bank teller) is busy serving customers. It is not a measure of the waiting time for each transaction.

A P value of 0.10 means that the server is busy serving customers 10% of the time, while the remaining 90% of the time customers are waiting for service. It does not give any indication of the waiting time for each transaction.
