Student's Final Grade A statistics professor investigated some of the factors that affect an individual student's final grade in her course. She proposed the multiple regression model Student's Final Grade A statistics professor investigated some of the factors that affect an individual student's final grade in her course. She proposed the multiple regression model , where y   is the final grade (out of 100 points), x <sub>1</sub> is the number of lectures skipped, x <sub>2</sub> is the number of late assignments, and x <sub>3</sub> is the midterm exam score (out of 100). The professor recorded the data for 50 randomly selected students. The computer output is shown below. THE REGRESSION EQUATION IS S = 13.74 R - Sq = 30.0%     {Student's Final Grade Narrative} Does this data provide enough evidence at the 5% significance level to conclude that the final grade and the number of late assignments are negatively linearly related? , where y   is the final grade (out of 100 points), x 1 is the number of lectures skipped, x 2 is the number of late assignments, and x 3 is the midterm exam score (out of 100).
