Answer

Brief Explanations:

  • When estimating a population proportion, using a sample statistic (A) is a key concept. The sample proportion is the best point estimate (B). A confidence interval (D) is constructed using the sample proportion. However, knowing the sample size (C) is not a main idea of estimating a population proportion itself. It is more about the relationship between sample and population in terms of proportion and estimation methods (point - estimate, confidence interval), not just the sample size knowledge.

Answer:

C. Knowing the sample size necessary to estimate a population proportion is important.
