The masses to the nearest kilogram of nine men were:

serious [3.7K]

Answer:

82 kg

Step-by-step 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.

$\frac{734}{9} =\\81.556$

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

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

I hope this helps! Let me know if you have any questions :)
