A sample of U of M students is selected. The distance X (in km) between a student's place of residence and the time Y (in minutes) it takes them to get to the university are recorded. The least squares regression line is calculated to be 17 = 2.3 + 1.73:. It is reported that 75% of the variation in time can be accounted for by its regression on distance. 17. What is the value of the correlation between distance and time? (A) 0.260 (13) 0.866 (C) 0.625 (D) 0.750 (E) 0.563
