It is believed that positive, self-affirming statements can lead to greater academic success on high- stakes assessments. In a recent study, 120 advanced algebra students were randomly assigned to two groups. One group was instructed how to write and recite daily positive self-affirmations while the other group did not do any affirmations. After one semester, all 120 students took the same algebra examination. Which of the following would be appropriate hypotheses for this study? (A) Ho: M1 = ₂ and Ha: 1 U2, where ₁ = mean score for those who used affirmations and µ/₂ = mean score for those who don't use affirmations. (D) Ho: H1 H2 and Ha: ₁2, where μ₁ = mean score for those who used affirmations and μ₂ = mean score for those who don't use affirmations. (E) Ho: H1 H2 and Ha: U12, where μ₁ = mean score for those who used affirmations and μ/₂ = mean score for those who don't use affirmations.
