Answer:
b) Since the y-values increase as the x-values increase, the scatter plot shows a positive association.
Explanation:
In a scatter plot:
- The explanatory (independent) variable is along the x-axis
 - The response (dependent) variable is along the y-axis
 
Correlation measures how closely two variables are linked. 
- Positive correlation: response variable increases as the explanatory variable increases
 - Negative correlation: response variable decreases as the explanatory variable increases
 
The given scatter plot shows the y-variable increasing as the x-variable increases. Therefore, this shows a positive correlation.
Therefore, the solution is:
b) Since the y-values increase as the x-values increase, the scatter plot shows a positive association.
