Test the hypothesis that two populations have equal means against either a one-sided or a two-sided alternative. Use the two-sample t test with conservative degrees of freedom if you do not have statistical software. Use the TI-83/84/89 or software if you have it. Recognize when the two-sample t procedures are appropriate in practice.
