To find the mean, we need to multiply each score by the number of students who received that score, add up those products, and then divide by the total number of students.
(60x9) + (65x5) + (70x1) + (75x6) + (80x2) + (85x3) + (80x1) + (95x4) = 3865
Total number of students = 31
Mean = 3865/31 = 124.6774194
Rounding to the nearest 10th, the mean score is 124.7.
