Solution

Finding the mean weight
The given observations are $30, 27, 36, 29, 32, 28, 33, 31, 38, 35$
We know that,
$Mean = \frac{Sum of observations}{Number of observations}$
Therefore,
$Mean weight = \frac{30 + 27 + 36 + 29 + 32 + 28 + 33 + 31 + 38 + 35}{10} = \frac{309}{10} = 30.9 kg$
Hence, the mean weight of given data is $30.9 kg$
