Two Means - Matched Pairs (Dependent Samples): Videos & Practice Problems

A study compares a new online homework system to a traditional homework system for college algebra students. Group $1$ uses the online system, and Group $2$ uses the traditional system. Their final exam scores are: Online: $n_1=16$, ${\bar{x}}_1=89$, $s_1=7$; Traditional: $n_2=18$, ${\bar{x}}_2=85$, $s_2=8$. At $\alpha =0.01$, is there sufficient evidence to claim the online system results in higher scores? Assume equal variances.
