Vedclass · Answer

(A) To find the median class,we first determine the total frequency $n = \sum f_i = 6 + 10 + 5 + 6 + 4 + 2 + 2 = 35$.The median class is the class interval corresponding to the cumulative frequency just greater than $\frac{n}{2}$.Here,$\frac{n}{2} = \frac{35}{2} = 17.5$.Let's calculate the cumulative frequencies $(cf)$:Class $10-20$: $cf = 6$Class $20-30$: $cf = 6 + 10 = 16$Class $30-40$: $cf = 16 + 5 = 21$Since $21$ is the first cumulative frequency greater than $17.5$,the corresponding class interval $30-40$ is the median class.
