Administrators have collected data (n=500) from a randomly selected high school in the state to investigate the impact of taking additional science courses on ACT score. Currently students are required to take only 2 science courses for graduation; however, it appears that students who take additional science courses score higher on the ACT. A regression has been conducted to determine the impact of the number of science course on ACT, controlling for GPA as well.

	Coefficient	Standard Error	t Stat	P-value	Lower 95%	Upper 95%
Intercept	4.88	5.30	0.92	0.37	-6.42	16.17
Number of Science Courses	2.04	0.85	2.40	0.03	0.23	3.85
GPA	4.27	2.27	1.88	0.08	-0.57	9.11
