A firm produces sugar packages in 2 Kg bags. The actual weight of the sugar in one of those bags is normally distributed with mean 2.04 Kg and standard deviation 0.08 (Kg). a) Calculate the probability that one randomly selected bag contains between 1.85 Kg and 2.15 Kg of sugar. b) A bag of sugar is identified as a “best quality" if it is included in the top 2% of all bags (in terms of weight). Find the minimum Kg needed to be qualified as "hest quality".
