Answer: 9

Explanation:

Formula : Mean =
\frac{\text{Sum of observations}}{\text{Number of observaions}}

Given: 5 students participated in a push-up competition.

The amount of push-ups each student completed is listed: 12, 7, 10, 11,5.

Mean =
(12+7+10+77+5)/(5)


=(45)/(5)=9

Hence, the mean number of push-ups = 9
