Find the missing frequency if the median for the given distribution is 24:

Text Solution

Verified by Experts


Here, N=62+p
Medain =24 M
`rArr` Median class is 20-30
`:. L_(1)=20,l_(2)=30 rArr i=30-20=10`
f=25,C30
Now, `:."Median" "M=l_(1)+(((N)/(2)-C))/(f)xxi`
`24=20+((((62)/(2)+p-30)/(2)))/(25)xx10`
`rArr4=(10)/(25)=((62+p-60)/(2))`
`rArr 20=p+2rArr p=18`
