In a study to compare the effectiveness of distance learning with traditional classroom instruction, 12 students took a business course online while 14 students took it in a classroom. The final exam scores for the online students averaged 76.8 with a standard deviation of 8.6 , and the final exam scores for the classroom students averaged 80.1 with a standard de- viation of 9.3. Can you conclude that the traditional classroom instruction was more effective?
