**MathGuru**, Wednesday, November 7, 2012 at 5:36pmTry an independent groups t-test. This will be a two-tailed test because the problem is asking if there is a difference, which could be in either direction.

Hypotheses:

Ho: µ1 = µ2 (1 = females; 2 = males)

Ha: µ1 ≠ µ2

Degrees of freedom = n1 + n2 - 2

I'll let you take it from here.
