Question

The Weibull density function is given by f(y) = 1 αmym−1 exp(−y m/α), y > 0, 0, otherwise. where α and m are positive constants. This density function is often used as a model for the lengths of life of physical systems. Suppose Y has the Weibull density just given. Find a. the density function of U = Y m . b. E Y k for any positive integer k .
