Given: correlation co-efficient, r = 0.97. Conclusion: strong, positive, linear relationship.

An analysis of the 4 solutions:

1) an increase in 1 variable will be accompanied by a decrease in the other variable. => it is a positive relationship, hence no.
2) there is no relationship between the two variables => if no r'ship, r should be 0, hence no
3) there is a relationship between the 2 variables but it is insignificant => 0.97 is a very strong relation, hence no.
4) an increase in one variable will accompany an increase in the other variable. => by elimination this should be the answer. final assessment: yes, due to positive relationship
