Answer:
The correct option is B.
Explanation:
The given graph represents the sales of sweaters and gloves at her store for the past ten winter weeks.
If the scatter points lie near to a straight line and the slope of the line is positive, then there is a strong positive linear correlation between two variables.
r=1 means strong positive correlation.
r=0 means no correlation.
r=-1 means strong negative correlation.
From the figure it is clear that the scatter points lie near to a straight line and the slope of the line is positive. So, there is a positive linear correlation between the sales of sweaters and gloves.
Therefore the correct option is B.
