Multiple Choice

TABLE 12-8
It is believed that GPA (grade point average, based on a four-point scale) should have a positive linear relationship with ACT scores. Given below is the Microsoft Excel output for predicting GPA using ACT scores based a data set of eight randomly chosen students from a Big Ten university.

-Referring to Table 12-8, 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.
