WebIn this case, we'll focus our attention on a hypothesis test for the difference in two population means μ 1 − μ 2 for two situations: a hypothesis test based on the t -distribution, known as the pooled two-sample t -test, for μ 1 − μ 2 when the (unknown) population variances σ X 2 and σ Y 2 are equal. a hypothesis test based on the t ... WebMar 27, 2001 · Equality essentially consists of a tripartite relation between two (or several) objects or persons and one (or several) qualities. Two objects A and B are equal in a certain respect if, in that respect, they fall under the same general term. ‘Equality’ denotes the relation between the objects compared.
