Question 1 of 12 - {1 E View Policies Current Attempt in Progress Suppose that the Canadian national average wait time for patients to see a doctor in a walk-in clinic is 21.3 minutes. Suppose such wait times are normally distributed with a standard deviation of 6.7 minutes. Some patients will have to wait much longer than the mean to see the doctor. In fact. based on this information, 3% of patients still have to wait more than how many minutes to see a doctor?
