Question

please solve this problem

Answer 1

We need to find the modified frequency first
it's formula is: MF=( minimum class interval * frquency of each class ) / class interval of each class
(minimum class interval=1)
1) 1/1*5=5
2) 1/1*3=3
3) 1/2*6=3
4) 1/2*12=6
5) 1/3*9=3
6) 1/5*10=2
7)1/2*4=2
Now make the histogram using the given data:

Age---------------------------------------No. of children
1-2 ---------------------------------------5
2-3 ---------------------------------------3
3-5 ---------------------------------------3
5-7 ---------------------------------------6
7-10--------------------------------------3
10-15-------------------------------------2
15-17-------------------------------------2
