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.
