A. 04950 B. 0.4370 C. 0.9310 D. 0.0570 A theorem that allows us to use the normal probability distribution to approximate the sampling distribution of sample means and sample proportions whenever the sample size is large is known as the approximation theorem normal probability theorem central normality theorem central limit theorem POP\"? The sampling error is the A. same as the standard error of the mean B. error caused by selecting a bad sample C. difference between the value of the sample mean and the value of the population mean D. standard deviation multiplied by the sample size The standard deviation of all possible x values is called the standard error of proportion mean deviation standard error of the mean central variation ppm?
