=+7.46 Accurate labeling of packaged meat is difficult because of weight decrease resulting from moisture loss

(defined as a percentage of the package’s original net weight). Suppose that the normal distribution with mean value 4.0% and standard deviation 1.0% is a reasonable model for the variable x 5 moisture loss for a package of chicken breasts. (This model is suggested in the paper

“Drained Weight Labeling for Meat and Poultry: An Economic Analysis of a Regulatory Proposal,” Journal of Consumer Affairs [1980]: 307–325.)
