Determining sample size from unknown population
If you want to determine the sample size from the unknown population then compute the minimum sample size you require,Â
choose a standard normal deviation, select a response value and confidence interval.Â
Then calculate the required sample size by using the formula, n = z 2 (p)(1-p)/c2
Where c is the confidence interval, p is the response and z is the standard normal deviation

On identifying these values, you can calculate sample size by using the formula
Sample size = (Z-score)2 * StdDev*(1-StdDev) / (margin of error)2
The confidence level corresponds to z-score
