question:
1.What percentage of variability in EdCollege is explained by its linear
regression on SmokeEveryday?
Is that -0.636
2.Which is the dependent variable and which is the independent variable?
Dependent: Edcoloege
Independent: Smokeeveryday
3.Comment on whether the choice of dependent and independent variables is
appropriate
because 0.636 is kind of large, so it is OK.

3 Mayabe vice versa is better
