Quizplus · Accepted Answer

The sample mean is an unbiased estimator of the population mean, meaning that on average it will estimate the true value. It also follows the central limit theorem, which states that as the sample size increases, the distribution of sample means will approach a normal distribution. Finally, the sample mean has the minimum variance among all unbiased estimators. Therefore, all of the given statements are true.
