Answer:
The correct option is 3.
Explanation:
If the scattered points lie near to a straight line which has positive slope, then the data represents the linear positive association.
If the scattered points lie near to a U-shaped curve, then the data represents the Nonlinear association
If the scattered points are not related to each other (neither linear association nor nonlinear association ), then the data represents no association.
If the scattered points lie near to a straight line which has negative slope, then the data represents the linear negative association.
From the given graph it is clear that the scattered points lie near to a straight line which has negative slope, therefore the data represents the linear negative association.
Therefore the correct option is 3.
