1. The problem statement, all variables and given/known data so, I'm given some sample data: electricity consumption on randomly selected n days, and asked to model the problem using Gamma distribution, then the question is to estimate percentage of days on which consumption was > 10 by using moment estimates. So, I can find the moment estimates for the two parameters: alpha number of exponentially distributed RVs each with mean lambda. But I do not know how to relate the estimates of the parameters to the question I am asked! could someone explain, please?
