Quizplus · Accepted Answer

To find the mean distance jumped by the top 10 athletes, we need to add up the distances jumped by all 10 athletes and then divide by 10. 
Adding up the distances given:
8.31 + 8.21 + 8.16 + 8.12 + 8.11 + 8.10 + 8.08 + 8.08 + 8.06 + 8.04 = 81.17
Now dividing by 10:
81.17 / 10 = 8.117
Rounding off to two decimal places gives the answer as 8.05 m (Option B).
