Answer 1

Answer :

given data :-

we have a data set : number of children

Now we need to construct a frequency distribution using six classes and to create a frequency polygon

there are 6 class we taken

(0-2), (3-5), (6-8), (9-11), (12-14), (15-17)

The Class-Frequency-Midpoint table is

	Class	Frequency	Mid point
1	0-2	14	1
2	3-5	16	4
3	6-8	4	7
4	9-11	5	10
5	12-14	2	13
6	15-17	2	16
