The graph displays data points corresponding to the number of students in a university campus and the number of student-organized events held per 100 students in one academic calendar year. All information present represents events that occurred during the last school year beginning in September. The dashed line runs through points (0,0) and (35,240). A total of 35 universities were surveyed.
Use the drop-down menus to fill in the blanks in each of the following statements based on the information given by the graph.
1. The number of universities that had at least 20 student-organized events per 100 students is about of the total number of universities surveyed.
2. The dashed line has a slope that is the slope of the regression line.

1) The number of universities that had at least 20 student-organized events per 100 students is about______________of the total number of universities surveyed.
Total Universities -35,
At least 20 (>=20), counting ( 20 to 25 )= 7, (26 to 30)= 5,
% of universities which had at least 20 events = (7+5) =12/35 = 12/36 (approx.) = 1/3 = 33.33%
Ans B.
2) The dashed line has a slope that is_______________the slope of the regression line.
Slope = rise/run i.e what is the rise per unit run.
Regression line & Dashed line - look at the intersection point of both the lines and its evident that Slope line is above the Regression line. We can infer that Slope of Dashed line is greater than Regression line.
Ans B
