Please answer Questions 3 and 4 based on the problem given below. Please do not use any computer software to answer these questions.

A single-server queuing system with an infinite calling population and a first-come, first-served queue discipline has the following arrival and service rates:

Î» = 16 customers per hour

Âµ = 24 customers per hour

Please use QM for Windows to solve the problem given below. Answer Questions 5 and 6 based on your results from QM for Windows.

A multiple-server queuing system with an infinite calling population and a first-come, first-served queue discipline has the following arrival and service rates:

Î»= the arrival rate = 50 customers per hour

Âµ = the service rate = 20 customers per hour

c = number of servers = 3
