for a frequency distribution,

So, total number of observation =(1+4+7+5+9+8)=34

It is a even number.

So, median is the value of average of values at (2n)th and (2n+2)th.

∴  Here, median is the average of the values at (234)th or 17th position and (234+2)th or 18th position.

 12+5=17

 17+9=26

 26+8=34

So, value of x at 17th position is
