Performs one-sided hypothesis testing for the difference between proportions.
boolean true if the null hypothesis (H0) cannot be rejected, false if the null hypothesis can be rejected
Having two sample proportions: one with mean `u1', size `n1' and one with size `n2' it conducts the following statistical test:
H0: p1-p2 >= dif Ha: p1-p2 < dif if `greater' is true or H0: p1-p2 <= dif Ha: p1-p2 > dif if `greater' is falseat `s%' significance level, where `dif' is the claimed difference between percentages and H0, Ha represent the null and alternative hypothesis respectively.
