**MathGuru**, Wednesday, April 4, 2012 at 7:48pmTry an independent groups t-test.

Hypotheses:

Ho: µ1 = µ2 -->population means are equal

Ha: µ1 does not equal µ2 -->population means are not equal

Use (n1 + n2 - 2) degrees of freedom for this test. Use a t-table to determine your cutoff or critical value to reject the null using 0.01 level of significance for a two-tailed test. If your test statistic exceeds the critical values from the table, reject the null and conclude a difference (µ1 does not equal µ2). If the test statistic does not exceed the critical values from the table, do not reject the null.

I hope this will help get you started.
