the means are unequal, in the case of a two-tailed test . or. the mean of B is greater than the mean of A, in the case of a one-tailed test. Note that the second of these takes the form that it does because the sample mean for B was greater than the sample mean for A.

Part of important studies within business and decision-making are the ones related to hypothesis for difference of population parameters; it is testing the difference between two population means or two population proportions. In order to run an efficient test you will need to choose a sample that represents your population effectively.
