In determining the sample size needed to estimate the population proportion p,we let the sample proportion $\hat { P }$ = 1 if we have no knowledge of even the approximate values of $\hat { P }$ .

Question

When we have no prior knowledge of the sample proportion $\hat{P}$, we typically use $\hat{P} = 0.5$ to maximize the sample size, as this provides the maximum variability and thus the most conservative estimate.
