Solution by Steps

step 1

Analyze the scatter plot for the direction of the association between the two variables

step 2

Determine if the points suggest a pattern as the population density increases

step 3

Observe if the rent for a 1-bedroom apartment increases or decreases with population density

step 4

Identify if the pattern is linear (points form a line), nonlinear (points form a curve), or if there is no discernible pattern

1 Answer

The best description of the relationship is (A) Positive linear association, (B) Negative linear association, (C) Nonlinear association, or (D) No association based on the observed pattern in the scatter plot.

Key Concept
