Education: Tutoring Does tutoring help support student achievement? In an experiment, a group of college students were randomly divided into two groups: the experimental group received peer tutoring along with regular instruction, and the control group received regular instruction with no peer tutoring.

There were n1 5n2 5 30 students in each group. The same math test was given to both groups at the end of the term. For the experimental group, the mean score was x1 5 89, with sample standard deviation s1 5 3.

For the control group, the mean score was x2 5 85, with sample standard deviation s2 5 4.1. Use a 5%

level of significance to test the hypothesis that there was no difference in the math scores between of the two groups after instruction.
