Question: Problem 3: On average 8 customers arrive at an ATM every hour. On average, a customer uses the ATM for 5 minutes. Assuming Poisson distribution

Problem 3: On average 8 customers arrive at an ATM every hour. On average, a customer uses the ATM for 5 minutes. Assuming Poisson distribution of the arrival rate and Exponential distribution of service times, what is the expected number of customers waiting to use the ATM (LQ) at a time, and what is the expected waiting time in the queue (Wg)? (Apply the single server queueing model. Maintain 3 decimal places. State the time unit for Wa) (2 marks]
