This statement is true. When we have some idea about the value of sample proportion, we can use it to calculate the required sample size using the formula n = (z^2 * p * q) / E^2, where z is the z-score corresponding to the desired level of confidence, p is the estimated sample proportion, q = 1-p, and E is the desired margin of error.
