Hospital B, because the average wait-time is only 90 minutes, rather than 135 minutes in Hospital A.
Hospital A, because with twice the standard deviation of Hospital B, it has twice the spread.
Neither, because for both hospitals, the probability of waiting less than 45 minutes is 2.275%.
Neither, because for both hospitals, the probability of waiting less than 45 minutes is 97.725%.
It is impossible for any patient to wait less than 45 minutes in either hospital unless the patient is in critical condition.
Cannot be determined.
