Problem 2 (Use 2 digits after decimal point.) Small boxes of NutraFlakes cereal are labeled "net weight 10 oz." Each hour, 4 boxes are weighed to check whether the process is in control. Nine hours of observations yielded the following data.

And compute UCL and LCL for Xbar chart. Q6 Compute UCL and LCL for R chart. 07 The net weight of NutraFlakes cereal in each box is designed to be 10.0 oz with a tolerance of +0.2 oz. Xablo bar computed in Q5 is used as an averagae net weight of the cereal box. The standard deviation is assumed to be 0.365. Comenta. (rocess capability index). 07 The net weight of NutraFlakes cereal in each box is designed to be 10.0 oz with a tolerance of +0.2 oz. Xdouble-bar computed in Q5 is used as an average net weight of the cereal box. The standard deviation is assumed to be 0.365. a: Compute Cpx (process capability index). b: What should the actual standard deviation of NutraFlakes cereal be to meet Six Sigma standard? (Note: Cyk-2 is equivalent to Six Sigma standard.)
