An engine manufacturer uses a forging process to make piston rings. The quality engineers want to assess the process capability. First, two operators are selectod and a gaugo R\&R was performed on the gauge used to measure. the diameters of the piston rings. The ANOVA results are below. The specification limits for piston ring dlameter are 74.0mm1.5mm. Gage R\&R Study - ANOVA Method Two-Way ANOVA Table With Interaction Variance components ring dameter are 740mm=1.5mm. Gage R\&R Study - ANOVA Method Two-Way ANOVA Table With interaction Variance Components The measurement system (is/is marginally/is not) capable because the P/T ratio equals \%.
