Q8 answer pls

Dear Student,
If your question is " If the class marks in a frequency distribution are 19.5, 26.5, 33.5, 40.5 then the class corresponding to the class mark 33.5 is'
then the solution is as follows:

We know that,

Class mark of the class interval, 16 – 23 =

Class mark of the class interval, 23 – 20 =

Class mark of the class interval, 30 – 37 =

Class mark of the class interval, 37 – 41 =

Thus, the class corresponding to the class mark, 33.5 is 30 – 37.

Regards!
