Explanation / Answer

1)

total n=20

arranging in ascending order

15 29 30 34 35 36 36 38 39 41 41 42 43 43 44 48 51 51 52 56

Median=(41+41)/2=41

so 3 groups or quartile

15 29 30 34 35 36 36 38 39

The first quartile Q1 is =35

41 41

The second quartile Q2 is=(41+41)/2=41

42 43 43 44 48 51 51 52 56

The third quartile Q3 is =48

Inquartile range= Q3-Q1

=48-35

=13

Inquartile range is 13

Outliers are (1) more than 48 + 1.5*IQR =67.5 or

(2) less than 48 – 1.5*IQR = 28.5, so no outliers.

There are no outliers
