Quizplus · Accepted Answer

The expected value of the sample mean is equal to the expected value of the population mean. This is because the sample mean is an unbiased estimator of the population mean, meaning that on average, the sample mean will equal the population mean. Therefore, the expected value of the sample mean and the expected value of the population mean are identical.
