The formula to find the minimum sample size(n) , if the prior population proportion is unknown:
, where E = margin of error ,
= critical z-value for confidence level c.
Given : E = 0.04
Z-value for 95% confidence = 1.96
So, the minimum sample size required =
Hence, the minimum sample size required = 601
