TABLE 13-8 It Is Believed That GPA (Grade Point Average, Based on Based

Multiple Choice

TABLE 13-8
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 Excel output from regressing GPA on ACT scores using a data set of 8 randomly chosen students from a Big-Ten university.

-Referring to Table 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 not sufficient evidence to show that ACT scores and GPA are linearly related.
B) Reject the null hypothesis; hence there is not sufficient 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.
