Attempt this question on a graph paper. The table shows the distribution of the daily wages, earned by 160 workers at a building site.
\begin{tabular}{|l|c|c|c|c|c|c|c|c|}
\hline Wages (₹) & \( 0-10 \) & \( 10-20 \) & \( 20-30 \) & \( 30-40 \) & \( 40-50 \) & \( 50-60 \) & \( 60-70 \) & \( 70-80 \) \\
\hline No. of workers & 12 & 20 & 30 & 38 & 24 & 16 & 12 & 8 \\
\hline
\end{tabular}
Using a scale of \( 2 \mathrm{~cm} \) to represent \( ₹ 10 \) and \( 2 \mathrm{~cm} \) to represent 20 workers, plot these values and draw a smooth ogive through the points. Estimate from the graph:
the upper and lower quartile wage earned by the workers.
