Aprocess analysis of a hospital's emergency room can answer all of the following questions except:
a. what is the average waiting time of a patient?
b. how many patients can be treated each day?
c. how busy are the physicians in the outpatient clinic?
d. how many beds are in the emergency room?

The answer is C.

Explanation:

The analysis of a hospital's emergency room can help identify the average waiting time, the number of patients that can be treated in one day and also how many beds there are in the said emergency room because all of these properties/statistics are both observable and measurable and they are relevant to the emergency room. But the information about how busy the physicians in the outpatient clinic are is not one of them since they are not related to the emergency room and take care of patients who do not need emergency care and do not need to spend bed time in the hospital.

So the exception is the option C.

I hope this answer helps.
