• A) Do not reject the null hypothesis; hence there is insufficient evidence to show that ACT scores and GPA are linearly related.
• B) Reject the null hypothesis; hence there is insufficient evidence to show that ACT scores and GPA are linearly related.
• C) Do not reject the null hypothesis; hence there is sufficient evidence to show that ACT scores and GPA are linearly related.
• D) Reject the null hypothesis; hence there is sufficient evidence to show that ACT scores and GPA are linearly related.
