Here, it can be observed that the data has class intervals of varying width The proportion of children per 1 year interval can be calculated as follows Age (in years) Frequency (Number of children) Width of class Length of rectangle 1 − 2 5 1

2 − 3 3 1

3 − 5 6 2

5 − 7 12 2

7 − 10 9 3

10 − 15 10 5

15 − 17 4 2

Taking the age of children on x-axis and proportion of children per 1 year interval on y-axis, the histogram can be drawn as follows

Age (in years)	Frequency (Number of children)	Width of class	Length of rectangle
1 − 2	5	1
2 − 3	3	1
3 − 5	6	2
5 − 7	12	2
7 − 10	9	3
10 − 15	10	5
15 − 17	4	2
