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.
