A study tracks the final exam scores for students in four different sections of a computer science course. The variable 's' represents an individual student's score. Which of the following expressions correctly represents the average final exam score for only the third section of the course?

Match each mathematical expression with its correct description by analyzing the components of the notation (e.g., bar, bold font, subscript).
