The table displays the scores of students on a recent exam. Find the mean of the scores to the nearest 10th. Score Number of Students: 60 2 65 2 70 4 75 6 80 6 85 1 90 8 95 2

Answer 1

To find the mean of the scores, we need to first calculate the sum of all the scores and then divide it by the total number of students.

(60*2) + (65*2) + (70*4) + (75*6) + (80*6) + (85*1) + (90*8) + (95*2) = 120 + 130 + 280 + 450 + 480 + 85 + 720 + 190 = 2015

Total number of students = 2 + 2 + 4 + 6 + 6 + 1 + 8 + 2 = 31

Mean = 2015 / 31 = 65

So, the mean of the scores is approximately 65.
