Performs one-sided hypothesis testing for the difference between the mean of two samples.
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 one with mean `u2', standard deviation `d2' and size `n2', it conducts 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 and H0, Ha represent the null and alternative hypothesis respectively.
