At a whiteware production facility, fridges which have been damaged are scrapped (costing $250) as it is too expensive to interfere with the production line and repair any damage. If damaged fridges occur so that the number has a Poisson distribution with the rate λ = 2.5 each day, then what is the mean and standard deviation of the cost of scrapping the fridges in a 30 day month?
