Conduct Repeated Measures ANOVA and compute PRE.

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 pretest, then participates in six sessions using the tutor, then is given a parallel posttest. The data are as follows:
