Answer 1

3) Here we have data:

10,15,30,31,32,33,34,35,36,37,38,38,39,40,41,42,43,44,45,46,47,48,49,50,60,70

a) Class width = (Maximum - minimum) / 8

= (70-10) / 8 = 7.5

Classes	frequency
10-17.5	2
17.5-25	0
25-32.5	3
32.5-40	9
40-47.5	7
47.5-55	3
55-62.5	1
62.5-70	1

   b)

c)

d)

Minimum = 10

First quartile = 33.75

Median = 39.5

Third quartile = 46.25

Maximum = 70

e)
