a) The size of the sampling error that comes from a random sample depends on both the variation in the population and the size of the sample being selected. b) If you increase your sample size, the sample mean will always get closer to the population mean c) Sampling error is the difference between the sample statistic and the population parameter d) If a sample is selected using random sampling methods, the primary reason that the sample mean might be different from the corresponding population mean is that the sample might be biased.
