Chunky Meatbots produces a wide variety of unorthodox bread sauces. The company’s three best-selling variants are The BLT Apprentice, The Submachine Bun, and Game of Scones. Each bottle containing these sauces is required to meet predetermined weight specifications, so that no single bottle contains greater or lesser sauce than the others. The company measures the mean weight per production run to determine if there are variances over or under the company’s specified upperand lower-level control limits. A production run that falls outside of the specified control limit does not meet quality standards and is investigated further by the management to determine the cause of this variance. The three Chunky Meatbots sauces had the following weight standards and production run data for the month of March:
