Try an independent groups t-test. This will be a two-tailed test because the problem is just asking if there is a difference, which could be in either direction.

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

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

I hope this will help get you started.
