The null hypothesis states that the mean score on Campus 1 is less than or equal to the mean score on Campus 2. Therefore, option D is the correct choice as it states H₀: µ₁ ≤ µ₂. Option A and B are incorrect as they do not address the hypothesis being tested, and option C is incorrect as it assumes the mean scores on both campuses are equal, which is not part of the hypothesis being tested.
