The table gives the frequency distribution of weights of 80 apples selected at random from a big consignment.
\begin{tabular}{|l|c|c|c|c|c|c|c|c|}
\hline Weight \( (g) \) & \( 110-119 \) & \( 120-129 \) & \( 130-139 \) & \( 140-149 \) & \( 150-159 \) & \( 160-169 \) & \( 170-179 \) & \( 180-189 \) \\
\hline Frequency & 5 & 7 & 12 & 20 & 16 & 10 & 7 & 3 \\
\hline
\end{tabular}
Draw both cumulative (less than) and cumulative (more than) ogives on a graph paper and determine the median weight of apples from the point of intersection of these two curves.
