Question

Based on the points you provided for the scatter plot, it appears that as the amount of time students slept the night before the exam increases, their exam scores also tend to increase. The scores start relatively low and rise more steeply after a certain point.
Given this description, the relationship shows a pattern that indicates a positive association, as higher sleep hours correspond to higher exam scores.
However, the rate of increase in exam scores appears to slow down after about 7 hours of sleep, which suggests that the relationship might not be perfectly linear throughout.
Therefore, the best description of the pattern of association for the scatter plot is:
**There is a positive nonlinear association.**
