**MathGuru**, Friday, January 18, 2013 at 8:50pmHere are a few hints:

1. Try an independent groups t-test to calculate the t-test statistic.

2. Degrees of freedom for an independent groups t-test is this:

n1 + n2 - 2

3. Compare your test statistic to the critical values listed. If the test statistic exceeds the critical values, reject the null and conclude a difference. If the test statistic does not exceed the critical values, do not reject the null (you cannot conclude a difference in this case).

I hope this will get you started.
