In order to meet government regulations, the contained weight of a product must at least equal the labeled weight 98% of the time. Control charts for X and s are maintained on the weight in ounces of the contents using a subgroup size of 10. After 20 subgroups, X-731.4 and Es 10.95. a- Compute 3-sigma control limits for X and s, and estimate the value of o, assuming that the process is in statistical control. b- If the label weight is 36 oz, and assuming that the process generates a normal distribution does it meet federal requirements? (Hint: calculate the probability that the contained weight is greater than 36 oz)
