Make a frequency table and then answer these questions:

(i) How many families have exactly 6 members?

(ii) How many have fewer than 5 members?

(iii) How many have just 2 members?

Now make three such questions of your own.

Answer 1

Frequency table of the given data can be drawn as follows:

Number of Member		Number of Family
2		1
3		3
4		1
5		1
6		5
7		2
8		2
9		3
10		1
13		1
Total		20

(i)

Frequency table shows that in 5 families there are exactly 6 members.

(ii)
