Hand simulation exercise to compute the average time in system and average number in system. There is a single server system that sees customer arrivals one at a time following a certain distribution. The server processes the customers one at a time on a first come first served basis. There is a buffer in front of the server where customers can wait if the server is currently serving another customer. The following table shows the interarrival time $($time since the previous arrival$)$ for the first six customers. The time required to serve each customer is provided. The simulation ends once the last customer $($customer #$6)$ leaves the system. Compute:

The average time in system for the customers based on the data.

The average number of customers in the system based on the data.
