Question

Quizplus · Accepted Answer

The most appropriate method for assigning the probability of more than 20 calls coming in per hour would be the relative frequency method, which involves analyzing past data to determine the frequency of occurrence of the event of interest. This method would provide a more objective and empirical estimate of the probability compared to personal, judgmental or subjective methods, which may rely on personal biases or perceptions. The classical method may not be appropriate as it assumes that events are equally likely and independent, which may not be the case in this scenario.
