The teacher found a correlation of .95 between study time and the final exam score. List 2 conditions that would be necessary to infer that studying “caused” students to score higher on the exam.

The following linear regression equation was determined from 100 students who reported how long they studied for the final exam, where X is the number of hours that students studied for the final exam, and Y is the final exam score Y = 85 + 2 (X) How many dependent variables are represented by this equation?
