Question

A course in mathematics is taught to 12 students by conventional classroom procedure. A second group of 10 students was given the same course by means of programed materials. At the end of the semester the same examination was given to each group. The 12 students meeting in the classroom made an average of 81 with a standard deviation of 4, while the 10 students using programed materials made an average of 81 with a standard deviation of 5. Test the hypothesis that the two methods of learning are equal using a 0.10 level of significance. Assume the populations to be approximately normal with equal variances.
