Answer 1

$\large\underline{\sf{Solution-}}$

Given frequency distribution table is

$\begin{gathered} \begin{array}{|c|c|} \bf{Class \: Interval} & \bf{frequency} \\ 5 - 10 & 4  \\10 - 15 & 45 \\15 - 20 & 20 \\20 - 25 & 13 \\25 - 30 & 9 \end{array}\end{gathered}$

Less than Cumulative frequency table :-

$\begin{gathered} \begin{array}{|c|c|} \bf{Less \: than} & \bf{frequency} \\ 10 & 4  \\15 & 49 \\20 & 69 \\25 & 81 \\30 & 91 \end{array}\end{gathered}$

More than Cumulative frequency table :-

$\begin{gathered} \begin{array}{|c|c|} \bf{More \: than} & \bf{frequency} \\ 5 & 91  \\10  & 87 \\15  & 42 \\20 & 22 \\25 & 9 \end{array}\end{gathered}$

Additional Information :-

Ogives are used to find the Median of the data.

The point of intersection where two ogives meet, there x - coordinate give the Median.
