Estimate process capability for the power supply voltage data in Table below. If specifications are at $350\backslash$pm $5$ V$,$ calculate Cp$,$ Cpk$.$ Interpret these capability ratios. If the Taguchi$’$s loss function is found to be L$($V$)=$$$120($X$-$T$)2,$ what is the expected loss? What is the sigma level of the process?
