Quizplus · Accepted Answer

An unbiased estimator is one where the expected value of the estimator equals the true population parameter being estimated. Therefore, option D is the correct answer as it states that the expected value will equal the population's parameters. Option A is incorrect as it states "perfectly" which may not always be the case. Option B is incorrect as it contradicts the definition of an unbiased estimator. Option C is also incorrect as the expected value can be negative or positive, depending on the specific estimator.
