The best report of the relationship between the number of absences and the final grade, given that the correlation coefficient \( r = -0.95 \), is:
As the number of absences increase, the final grade decreases.
This indicates a strong negative correlation between the two variables, meaning that higher numbers of absences are associated with lower final grades.
