Q 1-5. A dentist works from 9 am to noon, offering 1-hour appointments on the hour for routine cleanings (the first patient arrives exactly at 9 am, the second patient arrives exactly at 10 am...). The dentists schedule is always full, so she does not allow walk-ins. If she is free, the dentist begins the appointment when the patient arrives. The dentist finishes with each patient within 45 minutes, and patients arrive at the beginning of their appointment.

Why is a patients expected wait time different in the first versus the second scenario?
Group of answer choices
It isn't.
Because the dentist cannot fully balance the wait time caused by longer-than-average appointments with shorter-than-average service times.
Because variability in arrival times causes earlier-than-average arrivals to wait.
Because uncertainty in service times causes the dentists utilization to increase.
None of the above
