2. A computer programmer is considering two different computerized accounting systems. Two groups of accountants have been randomly selected to rate the extensiveness of the systems. For Program A, the mean rating was 87.2, the sample standard deviation was 8.7 and the sample size was 14. For Program B, the mean rating was 90.0 with standard deviation of 9.1 and sample size of 14. Does it appear that the two programs could be equally extensive?
