One way of stating H₀ for the t test for independent groups is µ 1 - µ 2 = 0. (Assume H₁ is nondirectional)

Question

Quizplus · Accepted Answer

This statement is true as H₀ refers to the null hypothesis for the t test for independent groups, which states that there is no difference between the means of the two groups (i.e. µ1 - µ2 = 0). The assumption given in the question (H₁ is nondirectional) means that the alternative hypothesis is simply that the means are different, without specifying whether they are higher or lower in one group compared to the other.
