Small boxes of NutraFlakes cereal are labeled "net weight 10 oz" Each hour, 10 boxes. are weighed to check whether the process is in control. Twelve hours of observations yiclded the following data. The net weight of NutraFlakes cereal in each box is designed to be 10.0 oz with a tolerance of 0.2oz. Xdoubleb computed in QS is used as an averagae net weight of the cereal box. The standard deviation is assumed to be 0.207 . a: Compute Cpk (process capability index). b: What should the actual standard deviation of NutraFlakes cereal be to meet Six Sigma standard? (Note: Cpk=2 is equivalent to Six Sigma standard.) Small boxes of NutraFlakes cereal are labeled "net weight 10 oz" Each hour, 10 boxes. are weighed to check whether the process is in control.
