Use to move the cursor to S x (it's the third thing in the list). The sample standard deviation will be on the screen. WebThen, by the central limit theorem, the standard deviation for the sample mean is =. The Empirical Rule, which applies to bell-shaped distributions, says that in approximately 95% of the samples, the sample mean, , will be within two standard deviations of the population mean μ. For our iTunes example, two standard deviations is (2)(0.1) = 0.2.
