emember the Cleveland Clinic case we discussed within Chapter $3.$ All involved steps in the Cleveland Clinic case added up to $28$ minutes per patient $($assuming no waiting$),$ and the bottleneck was the MRI machine with a processing time of $10$ minutes.

If the patients start to incur average wait times of $22$ minutes due to fluctuations in arrival times and service times, on average how many patients would be in the clinic?
