Calculate `Q_(1),Q_(3),D_(7)and P_(89)` from the following data :
`{:("Size",1,2,3,4,5,6,7,8,9,10,11),("Frequency",5,8,15,22,36,44,28,17,12,9,3):}`

Explanation

`Q_(1)` = Size of `((N+1)/(4))` th item
= Size of `((199+1)/(4))` th item
+ Size of 50th item =4
`Q_(3)` Size of `3((N+1)/(4))` th item
= Size of `3((199+1)/(4))` th item
=Size of 150 th item =7
`D_(7)` = Size of `3((N+1)/(10))` th item
= Size of `7((199+1)/(10))` th item
= Size of 140 th item =7
`P_(89)` Size of 89 `((N+1)/(100))`th item
= Size of 89 `((199+1)/(100))`th item
= Size of 178th item =9
Thus , `Q_(1)=4,Q_(3)=7,D_(7)=7,P_(89)=9.`
