For 50%, just enter 50 Acceptable Difference %Or Margin of Error. Alternatively, if you know the sample proportion, then it is difference between the assumed and the sample proportion. For 5%, just enter Sample SizeFinite PopulationEnter a number less than 50000Sample Size (1 Proportion Test) for finite populationMinimum sample require to check if your proportion matches with standard or known proportion for the given population Δ
