The mean of the random variable Y is also called the expected value or the expectation of Y. It is denoted E(Y). It is also called the population mean, often denoted µ. It is what we do not know in this example. A sample mean is typically denoted ȳ (read “y-bar”). It is calculated from a sample y_{1}, y_{2}, … , y_{n} of values of Y by the familiar formula ȳ = (y_{1}+ y_{2}+ … + y_{n})/n. The population means µ and a sample mean ȳ are usually not the same. Confusing them is a common mistake. Note that I have written “the population mean” but “a sample mean”. A sample mean depends on the sample chosen. Since there are many possible samples, there are many possible sample means.
