Problem $1$

Create a single$-$server queue model, use an interarrival rate of exponential$(1/120)$ entities per hour,

and a service rate of triangular $(160,175,190)$ entities per hour. Create a detailed sketch of the system,

ensuring that all relevant information is labeled accurately. Run your model for $100$ hours and report

the number of entities that were created, the number that completed service, and the average time

entities spend in the system. Include a screenshot of your simulation model as part of your solution.
