 Sample size     50 women     80 men
 Mean effect      7 women     6.95 men
 Sample variance  3 women      4 men
 -----------------------------------------
 I ran a 2-Sample T-test and got the following results:
 Ho: u(women)-u(men) = 0
 Ha: u(w)-u(m) is not zero
 ----------------
 test statistics: t = 0.08111...
 p-value: 0.9355...
 ---
 Conclusion: Since the p-value far exceeds alpha = 5%
 Fail to Reject Ho.
