Question

Customers arrive to a local bakery with an average time between arrivals of
5 minutes. However, there is quite a lot of variability in the customers’ arrivals, as
one would expect in an unscheduled system. The single bakery server requires an
amount of time having the exponential distribution with mean 4.5 minutes to serve
customers (in the order in which they arrive). No customers leave without service.
f.  Why are the estimated waits in this system so long? Are the assumptions behind
them reasonable? Why or why not?
