Let (X) be a random variable that has moment generating function (m(t)) that converges on some radius
Question:
Let \(X\) be a random variable that has moment generating function \(m(t)\) that converges on some radius \(|t| \leq b\) for some \(b>0\). Using induction, prove that
\[\mu_{k}^{\prime}=\left.\frac{d^{k} m(t)}{d t^{k}}ight|_{t=0}\]
