We want to compare the variability of two time-sharing systems according to the response time to an edit command. Observed response times (in milliseconds) for a number of queries on each system were collected. An Excel report on the equality of variances test is provided below: Equal Variances Test (F-Test) System A System B Average 1 692.941 678 Variance 308.559 260.571 Comments 17 15 Degree of freedom 16 14 IF 1.1842 P(F
