Quizplus · Accepted Answer

When estimating the population proportion, it is best to assume that the proportion is 50%, as this is the most conservative estimate. This means that we are assuming that the population proportion is the most uncertain and therefore the most variable, which results in wider confidence intervals and reduces the chances of making a type I error. This assumption is used when there is no prior information about the population proportion or when the sample size is small.
