WebMay 27, 2024 · The inequality you have asserted is false: A simple counter-example is X ∼ Bin(2, 1 2) and c = 1, which gives you the expectation: E( max (X, c)) = 3 4 ⋅ 1 + 1 4 ⋅ 2 = 5 4. For this counter-example we have: 5 4 = E( max (X, c)) > max (E(X), c) = 1. WebJun 18, 2024 · Since Y is independent of X, Z is also independent of X. For two independent random variables, the expectation of their product is the product of their expectations. This can be proved through the Law of Total Expectation.

WebIn the first case, the linearity of expectation gives us. E [ A] = E [ Y 3], which is easy to compute for Y ∼ Poisson ( λ). In the second case, you need to observe that. ∑ i = 1 n Y i ∼ Poisson ( n λ), i.e., the sum of n IID Poisson random variables is itself Poisson with rate parameter n λ. Consequently,

For Poisson distribution, V a r [ X] = λ and E [ X] = λ. Therefore: E [ X 2] = λ + λ 2. You can also use the Poisson's mgf: take the second derivative and set t = 0 to also find that E [ X 2] = λ + λ 2.
