1. Suppose you run a simple regression on a dataset with 123 colleges, with percent of students who are receiving financial aid as the dependent variable and the total in-state tuition, in $10,000 units. The unstandardized regression coefficient is 8.43. What is the correct interpretation of the regression coefficient?

		A $10,000 unit increase in tuition is associated with an 8.43 increase in the percent of students who are receiving financial aid.
		Institutions with high tuition have an 8.43 percent more students receiving financial aid than institutions with low tuition.
		A one percent increase in students receiving financial aid is associated with a 8.43 percent increase in tuition.
