In determining the sample size n for estimating the population proportion p,a conservative value of n can be obtained by using 0.50 as an estimate of p.

Question

Using 0.50 as an estimate for p in the formula for determining sample size maximizes the product p(1-p), which in turn maximizes the sample size n, making it a conservative estimate since it accounts for the highest possible variance.
