Question: part a ) Cp = 0 . 7 5 2 0 0 0 0 1 9 part b ) Cpu = USL - U /

part a) Cp=0.752000019
part b) Cpu= USL-U/(3*Sigma)
0.799396682
Cpl=u-LSL/(3*sigma)
0.708898944
Cpk=min(Cpl, Cpu)==>0.70889
part C) Calculated and compare the PCR Cpkm and Cpkm
Cpkm=(Cpk)/(1+(u-T/sigma)^2)^(1/2)
T=40 u=39.7 sigma=2.21
Cpkm 0.032783181=(0.70889)/(1+(39.7-40/(2.21))^(2))^(1/2)
part d)
Pactual = Pr{z<(35-39.7/(2.21))+[1-Pr{z<=(45-39.7)/(2.21)}]
sigma -2.126696833+2.398190045
=1-sigma(2.3919)
0.017+=1-.99159
0.00841
Pactual=0.02541
Ppotential =2*Pr{z
