Solution

Average of raw data is equal to sum of data divided by number of data.
$Average = \frac{Sum of data}{Number of data}$

$(i)$
$\begin{matrix} Average & = \frac{48 + 23 + 13 + 54 + 7}{5} = \frac{145}{5} = 29 \end{matrix}$

$(i i)$
$\begin{matrix} Average & = \frac{3 + 47 + 92 + 28}{4} = \frac{170}{4} = 42.5 kg \end{matrix}$
