Solution
Solution Steps
Step 1: Examining the Scatterplot for Outliers
There are no points that significantly deviate from the general cluster, so there are no outliers.
Step 2: Examining the Scatterplot for the Strength of the Relationship
The points are somewhat scattered, not tightly clustered along a specific pattern, which indicates a weak relationship.
Step 3: Examining the Scatterplot for the Type of Relationship
The points don't follow a straight-line pattern. Instead, there's a curve suggesting a nonlinear relationship.
Step 4: Examining the Scatterplot for Direction
As x increases, y tends to decrease. This indicates a negative relationship.
Final Answer:
The correct descriptors for the scatterplot are: Weak, Nonlinear, Negative, and NO Outlier(s) Present.
