The sample proportion that requires the largest number of work sampling observations for a given confidence level and allowable error is 0.50. This is because the formula for determining sample size in this context includes the term p(1-p), which reaches its maximum value when p = 0.5, indicating the highest variability and thus the largest sample size needed to achieve a certain level of precision.
