The label on a pack of coffee states "1 kg net". The filling machine is set to an average weight of u = 1.003 kg. The standard deviation of the filling weights is o = 0.01 kg. a. What is the probability that the average net weight of a random lot of 100 packs is less than 1 kg? b. What is the probability that the total lot of 100 packs weighs more than 100.5 kg net? c. If the net weights of filled packs are normally distributed, what is the probability that a randomly selected package weighs less than 1 kg? The label on a pack of coffee states "1 kg net".
