(D) Arranging the data in ascending order,we get:$22, 34, 39, 45, 54, 54, 56, 78, 84$Here,the number of observations $n = 9$,which is an odd number.Therefore,the median is the value of the $\left(\frac{n+1}{2}\right)^{th}$ term.Median $= \left(\frac{9+1}{2}\right)^{th}$ term $= 5^{th}$ term.Looking at the ordered data,the $5^{th}$ term is $54$.Thus,the median is $54$.

Class	$0-10$	$10-20$	$20-40$	$40-70$	$70-100$
Frequency	$15$	$13$	$28$	$36$	$27$

The median of the data $78, 56, 22, 34, 45, 54, 39, 54, 84$ is
