The hardness of a sample from each lot or tablets is measured in order to control the compression process. The process has been operating in control with mean at the target value u 11.: Kilograms {ng and estimated standard deviation 5 = 0 2 Kg The table below gives three sets 0| data, each representing it nor 20 successive samples One set remains in control at the target value. In a second set the process mean ushilts suddenly to a new value In a third the process mean drifts gradually '1} What are the center line and control limits for an 1 chart I-Oi' this process?
