Example 1 :

reference set here can be the number of student

in a class. Student should know how manystudents in one class. They should also be able to

gives an estimate for the number of students in

the school.

adding the num of hours. The answer can be

estimated using a very important techniquecalled sampling. Take a survey of sum of the

children in the school ( say one class or 2

students in each class and then scale up)
