The Newport Health Clinic experiments with two different configurations for serving patients. In one configuration, all patients enter a single waiting line that feeds three different physicians. In another configuration, patients wait in individual lines at three different physician stations. Waiting times (in minutes) are recorded for 10 patients who are randomly selected from each configuration. Single line: 65, 66, 67, 68, 71, 73, 73, 77, 77, 77

Multiple lines: 42, 54, 58, 62, 67, 77, 77, 85, 93, 100

Which formula should you use to calculate the variances of the waiting times for each group?

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
