SCENARIO 13-8
-Referring to Scenario 13-8, what are the decision and conclusion on testing whether there is any
Linear relationship at 1% level of significance between GPA and ACT scores?
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.

The p-value (0.012) is greater than the significance level (0.01), so we fail to reject the null hypothesis. This means that there is not enough evidence to conclude that there is a linear relationship between GPA and ACT scores.
