If your test statistic is symmetrically distributed, you can select one of three alternative hypotheses. Two of these correspond to one-tailed tests and one corresponds to a two-tailed test.However, the p-value presented is (almost always) for a two-tailed test.his means that .05 is in one tail of the distribution of your test statistic.
