Problem 1. (15 points) A plant supervisor is interested in budgeting weekly repair costs for a certain type of machine. Records over the past years indicate that these repair costs have an exponential distribution with mean 20 for each machine studied. Let Y1, ..., Y5, denote the repair costs for five of these machines for the next week. Find a number c such that Ρ(ΣΥ, >c) = 0.10 (Hint: If Y has an exponential distribution with mean 0, show that U = 28/0 has a x2 distribution with 2 df.) i a
