Answer #1

a) Arrange the given data in ascending order

1 19
2 21
3 25
4 28
5 29
6 32
7 34
8 46

Q1 = (21 + 25)/2 = 23

Q3 = (32 + 34)/2 = 33

IQR = 33 - 23 = 10

Lower fence = Q1 - 1.5*IQR = 23 - 1.5*10 = 8

Lower fence = Q1 + 1.5*IQR = 23 + 1.5*10 = 38

For this data set 46 is an outlier

b)

1 65
2 82
3 89
4 90
5 93
6 94
7 97
8 100
9 101

Q1 = (82 + 89)/2 = 85.5

Q3 = (97 + 100)/2 = 98.5

IQR = 98.5 - 85.5 = 13

Lower fence = Q1 - 1.5*IQR = 85.5 - 1.5*13 = 66

Lower fence = Q1 + 1.5*IQR = 98.5 + 1.5*13 = 118

For this data set 65 is an outlier

c)

1 175
2 371
3 489
4 527
5 1007

Q1 = (175 + 371)/2 = 273

Q3 = (527 + 1007)/2 = 767

IQR = 767 - 273 = 494

Lower fence = Q1 - 1.5*IQR = 273 - 1.5*494 = -468

Lower fence = Q1 + 1.5*IQR = 767 + 1.5*494 = 1508

For this data set there is no outlier
