it is believed that gpa (grade point average, based on a four point scale) should have a positive linear relationship with act scores. attached below is the technology output for predicting gpa using act scores based on a data set of 8 randomly chosen students from a big-ten university. what are the decision and conclusion on testing whether there is any linear relationship at 1% level of significance between gpa and act scores? loading... click the icon to view the technology output. question content area bottom part 1 a. reject the null hypothesis; hence there is insufficient evidence to show that act scores and gpa are linearly related. b. do not reject the null hypothesis; hence there is insufficient evidence to show that act scores and gpa are linearly related. c. reject the null hypothesis; hence there is sufficient evidence to show that act scores and gpa are linearly related. d. do not reject the null hypothesis; hence there is sufficient evidence to show that act scores and gpa are linearly related.
