Performs one-sided hypothesis testing for the difference between means.
boolean true if the null hypothesis (H0) cannot be rejected, false if the null hypothesis can be rejected
Having two samples: one with mean `u1', standard deviation `d1' and size `n1', and the other with mean `u2', standard deviation `d2' and size `n2'. We conduct the following statistical test:
H0: u1-u2 >= dif Ha: u1-u2 < dif if `greater' is true or H0: u1-u2 <= dif Ha: u1-u2 > dif if `greater' is falseat `s%' significance level, where `dif' is the claimed difference between means.
