An educational study uses a simple pre-post design to assess the efficacy of a computer tutor for solving inequalities. Twelve pilot students participate. Each student is given a pre-test, then participates in six sessions using the tutor, then is given a parallel post-test. The data are as follows:

Subj.	pre	post
1	10	13
2	11	6
3	9	18
4	13	17
5	8	14
6	7	11
