which of the following correlations demonstrates a casual relationship?
1)the distance students live from school, and the time it takes to walk there.
2)the amount of money received for allowance and the number of dvd's purcashed.
3)the number of hours spent studying and the grades received on exams.
4)high schools students' ages and the number of hours they asleep.

The word you should have used to decribe the relationship is "causal", not "casual". I would say only #1 decribes a causal relationship. The two variables in #2 and 3 may have a correlation, but one variable does not always lead to or "cause" he other. #4 is likely to have no connection at all.
