Draw an ogive for the following frequency distribution and from it estimate the median marks and the number of students who obtained more than \( 75 \% \) marks.
\begin{tabular}{|l|c|c|c|c|c|}
\hline Marks & \( 0-9 \) & \( 10-19 \) & \( 20-29 \) & \( 30-39 \) & \( 40-49 \) \\
\hline No. of students & 5 & 9 & 16 & 22 & 26 \\
\hline \multirow{5}{*}{} & \( 50-59 \) & \( 60-69 \) & \( 70-79 \) & \( 80-89 \) & \( 90-99 \) \\
\cline { 2 - 6 } & 18 & 11 & 6 & 4 & 3 \\
\hline
