Performs hypothesis testing about differences between proportions.
boolean true if we cannot reject the null hypothesis (H0), false if we can reject the null hypothesis
Having two sample proportions: one with percentage `p1' and size `n1' and one with percentage `p2' and size `n2' it conducts the following statistical test:
H0: p1-p2 = dif Ha: p1-p2 != dif at `s%' significance level.where `dif' is the claimed difference between the two percentages and H0, Ha represent the null and alternative hypothesis respectively.
