Find the Cp and Cpk indexes for a process with μ = 0.426, σ = 0.001, LSL = 0.423, USL = 0.432. How would you rate the capability of this process? Explain.
Answer to relevant QuestionsFind the Cp and Cpk indexes for a process with μ = 55.4, σ = 0.1, LSL = 55.2, USL = 55.9. How would you rate the capability of this process? Explain. Based on the cost of sampling and the presumed accuracy required, would sampling or 100 percent inspection be used to collect data on (a) The horsepower of each engine being in- stalled in new cars; (b) The fuel ...17.48 Refer to the bolt strength problem 17.47. Assume μ = σ 6,050 and 5 100. Use the following 24 individual bolt strength observations to answer the questions posed. (a) Prepare a histogram and/or normal probability ...A box of Wheat Chex cereal is to be filled to a mean weight of 466 grams. The lower specification limit is 453 grams (the labeled weight is 453 grams) and the upper specification limit is 477 grams (so as not to over fill ...Refer to the paint problem 17.49 with 51.00 and μ = .07. With n = 5, LCL = .906 and UCL = 1.094. Below are five sets of 20 sample means using n = 5. Test each set of means for the pattern suggested in the column heading. ...
