Find the Gini coefficient of income for both years. (Round your answers to three decimal places.) after beforeIf X is an exponential random variables with rate 1, then its distribution function is given by F(x) = 1 − e−x Show that x = − ln(1 − u).If we let RX(t) = ln MX(t), show that R X(0) = μ and RX(0) = σ2.
