A machine makes parts that weigh an average of 3kg with a standard deviation of 480 g. We consider two batches of 920 pieces each.
Describe completely this situation, define all the data, explain the method and all steps of computation. Express the probability that the weight difference between these 2 batches is greater than 4.5 kg. Then, we extract two batches of 1400 pieces each. What is the probability that with the weight difference is less than 6kg?
