------
Ho: u1-u2 = 0
Ha: u1-u2 # 0
-----------
sample mean 1 9.31
sample mean 2 7.4
t = 3.095390373
P-value 0.00127807
-----
If your p-value is correct, reject Ho because the p-value is
less than 5%.
Conclusion: There is no statically significant different between
the proportions at the 5% level of significance.
