Ans. We find all using R:
>
x<-c(-40,5,10,13,21,25,29,30,33,37,40,41,47,55,67,71)
> min(x)
[1] -40
> summary(x)[2]
1st Qu.
19
> median(x)
[1] 31.5
> summary(x)[5]
3rd Qu.
42.5
> max(x)
[1] 71
> boxplot(x)
(a) .
Min = - 40
Q1 = 19
Median = 31.5
Q3 = 42.5
Max = 71
(b). Yes, using box plot we can say that there is an outlier which is - 40.
(c). Box plot is given above.
