Assume that Y denotes the number of bacteria per cubic centimeter in a particular liquid and that Y has a Poisson distribution with parameter . Further assume that varies from location to location and has a gamma distribution with parameters and , where is a positive integer. If we randomly select a location, what is the a expected number of bacteria per cubic centimeter? b standard deviation of the number of bacteria per cubic centimeter?
