Part 1 of 2 parts A Six Sigma project team is working to improve manufacturing capability for their company’s number #1 product, the Whirligig Model-[d]. The team knows they need to conduct a gauge R&R study before establishing the process performance baseline. For the study, three technicians measured the same ten parts, three times each (total of 90 measurements). The target for the part characteristic is 5000, with USL = 5300 and LSL = 4700. The ANOVA gave the following estimates: σRPT = [rpt]; σRPD = [rpd]; σTOTAL = 100 Estimate the % Repeatability & Reproducibility. (Answer as a percentage rounded to two decimal places)
