Answer 1

Solution-:

Option (B) 32 is correct.

By using R-Software:

> x=c(30,32,30,33,33,30,35,32,40,36,36,34,29,36,30,25,20,32,32,32);x
[1] 30 32 30 33 33 30 35 32 40 36 36 34 29 36 30 25 20 32 32 32
> Med=median(x);Med # Median
[1] 32

R-Code:

x=c(30,32,30,33,33,30,35,32,40,36,36,34,29,36,30,25,20,32,32,32);x
Med=median(x);Med # Median
