Please do not give solution in image formate thanku.  The specification for a plastic liner for concrete highway projects calls for a thickness of 6.0 mm ± 0.1 mm. The standard deviation of the process is estimated to be 0.02 mm. The process is known to operate at a mean thickness of 6.03 mm. What is the Cp and Cpk for this process? Determine whether this process meet 3-sigma requirements, 6-sigma requirements, or doesn’t meet any requirements.
Linda Boardman, Inc., an equipment manufacturer in Boston, has submitted a sample cutoff valve to improve your manufacturing process. Your process engineering department has conducted experiments and found that the valve has a mean (u) of 12.00 and a standard deviation (o) of 0.06. Your desired performance is u = 12.00 ±3 standard deviations, where o = 0.070. For the given information, the process capability index (Cpk) = (round your response to three decimal places)
Linda Boardman, Inc., an equipment manufacturer in Boston, has submitted a sample cutoff valve to improve your manufacturing process. Your process engineering department has conducted experiments and found that the valve has a mean (μ) of 12.00 and a standard deviation (a) of 0.04. Your desired performance is μ = 12.00 ±3 standard deviations, where σ = 0.020. For the given information, the process capability index (Cpk) = 0.875 (round your response to three decimal places).
