Question

5 students participated in a push-up competition.

The amount of push-ups each student completed is listed: 12, 7, 10, 11,5
What was the mean number of push-ups?

Answer 1

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
