It is believed that students who begin studying for final exams a week before the test score differently than students who wait until the night before. Suppose you want to test specifically that students who study earlier have an average score that is different from the average score for students who wait to study. What are the hypotheses for this test if early studiers are group 1 and procrastinators are group 2?

Question 13 options:

1)

 HO: μ1 = μ2
HA: μ1 ≠ μ2

2)

 HO: μ1 ≥ μ2
HA: μ1 < μ2

3)

 HO: μ1 ≠ μ2
HA: μ1 = μ2

4)

 HO: μ1 ≤ μ2
HA: μ1 > μ2

5)

 HO: μ1 > μ2
HA: μ1 ≤ μ2
