Question

When you are testing a hypothesis against a two-sided alternative, then the alternative is written as A)E(Y)> µ_Y,0. B)E(Y)= µ_Y,0. C) $\bar { Y }$ ? µ_Y,0. D)E(Y)? µ_Y,0.

Quizplus · Accepted Answer

When testing against a two-sided alternative, we are looking for differences in both directions from the null value. Therefore, the alternative hypothesis is stated as E(Y)≠µ_Y,0.
