Performs hypothesis tests about differences between means.
boolean it returns true if we cannot reject the null hypothesis (HO) or false if the null hypothesis can be rejected
Given two samples where the means of the two samples `u1', `u2'; the standard deviations `d1', `d2'; and the sample sizes `n1', `n2' are known. We can conduct the following statistical test:
H0: u1-u2 = dif Ha: u1-u2 != dif at `s%' significance level.where `dif' is the claimed difference between the two means and is a percentage.
