Calculate the mean mass​

Answer 1

82kg is the answer I did research and I’m 90% sure that the answer

Answer 2

82 kg

Explanation:

To find the mean of a set of values, we must add them up and divide by the number of values.

Step 1, adding the values:

`75+68+78+82+85+90+88+92+76=\\734`

Step 2, dividing by the # of terms:

There are 9 terms in total.

`(734)/(9) =\\81.556`

To the nearest kilogram, we can round 81.556 into 82.

The mean mass of the 9 men was
`\fbox{82}` kg.
