WebMay 22, 2024 · $\begingroup$ @drhab No, the population mean $\mu$ is not a random variable, but a fixed number (a parameter). The sample mean $\bar{X}$ is a random variable (a statistic) when the sample values are considered random variables. But the sample mean $\bar{x}$ of a given sample is a fixed number, and thus not a random variable. … WebParameters are the unknown values of an entire population, such as the mean and standard deviation. Samples can estimate population parameters but their exact values are usually unknowable. Parameters are also the constant values that appear in probability functions. These parameters define the shape of probability distributions. Parameters are typically …
