SECTION A (You should attempt all 10 questions) A1. The sample mean is an unbiased estimator for the population mean. This means: (A) The sample mean always equals the population mean. (B) The average sample mean‚ over all possible samples‚ equals the population mean. (C) The sample mean is always very close to the population mean. (D) The sample mean will only vary a little from the population mean. A2. The central limit theorem tells us that the sampling distribution of the mean is approximately
