Question

A computer company conducted a “new and improved” course designed to train its service representatives in learning to repair personal computers. Twenty trainees were split into two groups on a random basis: 10 took the customary course and 10 took the new course.
At the end of 6 weeks, all 20 trainees were given the same final examination.
For the following results, test the null hypothesis that the new course was no better than the customary course in terms of teaching service representatives to repair computers (higher scores indicate greater repair skills). What do your results indicate?
