Assignment:
In a cosmetics manufacturing company, the QA department measures the weight of the products after packaging. One particular product is supposed to weigh between 1 to 1.1 lbs. Over a period of 30 days, data collected form the shipping department indicates that the product weight is normally distributed and the associated control chart of weights is stable. The subcategory sample size used for the control chart was four products every two hours. The control chart calculations indicated that the grand process average is 1.056 lbs. and the average range is 0.05. As a Lean Six Sigma Green Belt, estimate the percent of products that could have been shipped underweight and overweight using the standard normal distribution tables.
