11.3. For the weight of contents of a package of a food product, the minimum specification for weights is 500 g. From past experience sx, is known to be 0.6 g. Taking m¼m1¼501 g as the RQL, and m¼m2¼502 g as the AQL, and using respective risks a and b both at 0.05, find a sampling plan. Assume normal distribution of the x’s. Sketch the OC curve, Pa vs. m, labeling axes.
