5.61	1.74	28.63	9.89	13.94	5.44	2.20	4.23
193.66	17.00	21.23	8.78	13.38	15.56	2.83	6.14
74.58	13.77	20.54	6.72	9.84	4.50	1.48	4.25
27.80	16.96	18.95	4.06	8.36	3.64	0.65	4.45
31.50	11.14	22.61	6.82	8.64	4.76	1.46	3.39

(c) Identify any unusual values. (Round your answers to 2 decimal places.)

Answer 1

Ans:

We arrange the observation in ascending order

Here

IQR =Q3-Q1=20.7125-6.44=14.3

Ll= Q1-1. 5×IQR=6.44-1.5×14.3=-15.01

UL=Q3+1.5×14.3= 42.1525

The unusual observations are 74.58,193.66

Because the this value doesn't lie within the Ll and Ul
