Solution

Range is the difference between the highest and the lowest observation of the data.
Highest weight from the following data is $3.1 k g$
lowest weight from the following data is $2.1 k g$
so, range=Highest weight-lowest weight
$\Rightarrow$ range $= 3.1 - 2.1 = 1 k g$
so, the range of the given data is $1 k g$ .
