Customers arrive at a system with a single-server queue via a Poisson

Customers arrive at a system with a single-server queue via a Poisson process with rate of 1 customer every 5 minutes. The service time of each customer is exactly 4 minutes. There are 6 Questions (Pay attention to the units. Numerical answers only): Q1: Identify the queuing model: Q2: Determine A: 12 customers/ hour Q3: Determine : 15 costomers/ hour Q4: Is the system stable? Q5: Determine the average number of customers in the queuing system. Q6: Determine the average waiting time of a customer in the queue.
