Part 2) URGENT CARE (8 pts)

You recently started working as a nurse manager at a larger local urgent care facility.Because the center is so new (and a bit fancier than most) many patients come here expecting a bit of a wait before they can be seen.Out of curiosity, on a particularly busy day you write down how many minutes a random sample of patients has to wait before being seen by one of the medical staff.

Using a significance level of 0.05, test whether the average wait time is less than 15 minutes.
