Thread: Normal distribution

Fertiliser is packed in (nominally) 5kg bags. The packer has set his machinery to give bags of average weight 5.1 kg and he knows that the distribution of bag weights will be normal with standard deviation 0.05kg. A farmer buys 10 bags at a time. What is the distribution of mean weight of bags per purchase?
