Answer 1

Answer:

The Sum of upper limit of median class and modal class=32

Step-by-step explanation:

Modal class: That class whose frequency is highest.

By definition of modal class

Modal class=8-16

Upper limit of modal class=16

Class:0-8 8-16 16-24 24-32 32-40

Freq : 12 26 10 9 15

C.f: 12 38 48 57 72

Sum of frequencies=12+26+10+9+15=7212+26+10+9+15=72

n=72 =Even

Median class=\frac{(\frac{72}{2})^{th}+(\frac{72}{2}+1)^{th}}{2}=\frac{36th+37th}{2}=\frac{38+38}{2}=38

It lies in interval 8-16

Median class=8-16

Upper limit of median class=16

Sum of upper limit of median class and modal class=16+16=32
