WebJan 7, 2024 · X is a random variable with mean μ, and there is a sample of size n: X 1, X 2, ⋯, X n. Then what is the expected value of the sample mean X ¯? This is what I thought: X ¯ = 1 n ( X 1 + X 2 + X 3 + ⋯ + X n), thus X ¯ is a certain value (constant), therefore E ( X ¯) = X ¯. Similarly, X ¯ 2 is also a certain value (constant) and E ( X ¯ 2) = X ¯ 2. the future face cover creamWebus consider the distance to the expected value i.e., jX E[X]j.
