text: This means that the sample mean x̄ is a random variable!
text: Because the sample mean x̄ is a random variable, the sample mean itself has a mean and a standard deviation, and thus has a probability distribution.
text: The sample mean is a random variable, because its value depends on what the particular random sample happens to be.
text: This shows us that the sample mean is a random variable!
