An important factor in selecting software for word-processing and database management system is the time required to learn how to use the system. To evaluate three file management systems, a firm designed a test involving five word-processing operators. Since operator variability was believed to be a significant factor, each of the five operators was trained on each of the three file management systems. The data obtained follow. Operator System A B C 1 16 16 24 2 19 17 22 3 14 13 19 4 13 12 18 5 18 17 22 Use α = 0.05, test to see whether there is any difference in the mean training time (in hours) for the three systems.
