What is another name for the standard deviation of the variable x overbar? What is the reason for that name? Choose the correct answer below. A. Another name is sample mean because the standard deviation of x overbar determines the average amount of deviation to be expected when a population mean is estimated by a sample mean. B. Another name is sampling error of the mean because the standard deviation of x overbar determines the amount of variation to be expected when a population mean is estimated by a sample mean. C. Another name is standard error of the mean because the standard deviation of x overbar determines the amount of sampling error to be expected when a population mean is estimated by a sample mean. D. Another name is standard change of the mean because the standard deviation of x overbar determines the amount of variation to be expected when a population mean is estimated by a sample mean.
