What is the point estimator of the population proportion denoted as?

The point estimator of the population proportion is denoted by p̂ (pronounced "p-hat"), which is commonly represented as p. In this context, p̅ is used to represent the sample mean, rather than the sample proportion. When we are estimating the population proportion based on sample data, we typically use p̂, which is calculated by taking the number of successes in the sample divided by the total number of observations in the sample. This value serves as a best guess or estimate of the true population proportion π, which is the actual proportion in the entire population.

In summary, the notation p is designated for the population proportion, but p̂ specifically stands for the estimate derived from the sample data. Hence, in the context of the question, while p̅ represents the sample mean, it is not the correct notation for the point estimator of the population proportion, making the choice of p̅ suitable for the average but not for the point estimation of population proportion.
