Question

The U.S. Department of Veterans Affairs mandates two day classes on sexual harassment for new employees. As a potential cost reduction, the personnel office is considering switching to an online course. There is concern that performance will be lower with the computer, self-paced based training. The Department conducts a trial with new employees where a random group are assigned the online system. After either the online (6 subjects) or in-class training (8 subjects), employees are assessed two weeks after training with a standardized test concerning knowledge of sexual harassment regulations and behavior with scores ranging 0-100 (100 is the best score). Data is as follows: (C11PROB3.SAV) In-class: 70, 70, 60, 60, 65, 55, 65, 80 On-line: 75, 65, 80, 90, 70, 75

What is the standard error of the difference in means (to the hundredth and you can be off as much as +/- 0.15) ?
