The table shows the times of $30$ children took to complete a long distance race. Draw a histogram of this.

$\begin{array}{|cc|}\hline \text{ Time }\left(\mathbf{min}\right)& \text{ Number of children }\\ 10-13& \frac{x}{4}\\ 13-16& 5\\ 16-19& 12\\ 19-22& x\\ 22-25& 3\\ \hline\end{array}$

Obtain the range of the data

The table below given the amount of water $50$ households are

$\begin{array}{|cc|}\hline \begin{array}{c}\text{ Amount of water }\\ \text{ (litres) }\end{array}& \text{ Number of households }\\ 0-500& 3\\ 500-1000& \frac{x}{2}\\ 1000-1500& 7\\ 1500-2000& x\\ 2000-2500& 14\\ 2500-3000& 8\\ 3000-3500& 3\\ \text{ Total }& 50\\ \hline\end{array}$

See how this data is represented by a histogram. Also obtain the range of the data
