Answer 1

a) The frequency distribution is

Class Interval
LL	UL	f
0	4	3
5	9	5
10	14	1
15	19	4
20	24	2
25	29	5
	Total =	20

b) The relative frequency is calculated as the following table

Class Interval			Relative
LL	UL	f	frequency
0	4	3	0.15
5	9	5	0.25
10	14	1	0.05
15	19	4	0.2
20	24	2	0.1
25	29	5	0.25
	Total =	20

c)

Correct answer: (a) since frequencies are 3,5,1,4 and 2,5

d)

Correct answer: (a) since relative frequencies are 0.15, 0.25, 0.05, 0.2, 0.1 and 0.25
