How to determine the sample size with pre defined degree of

Why Sampling?  
 
We come across situations whose where we would like to know 
about vast population. 
But the factors like time, money, cost and large size of the 
population make it almost impossible to go for the complete 
enumeration of all the population.

population make it almost impossible to go for the complete 
enumeration of all the population. 
Sampling Theory 
Instead we can select a representative or part of the population 
(known as sample) & infer about the entire population on the 
basis of our knowledge about the sample.  
This is the basis of Sampling Theory.

samples drawn from it.
