In testing the hypotheses H₀: π ≤ π₀, H₁: π π₀, we would use a right-tailed test.

Question

In testing the hypotheses H₀: π ≤ π₀, H₁: π > π₀, we would use a right-tailed test.

Quizplus · Accepted Answer

The null hypothesis is that π is less than or equal to π₀, and the alternative hypothesis is that π is greater than π₀. A right-tailed test is appropriate for testing a one-sided alternative hypothesis where the direction of the effect is expected to be in the positive direction, which is the case for the alternative hypothesis in this scenario. Therefore, the answer is A.
