Answer:
a, a, b,b
Step-by-step explanation:
Upper bound: 475+50= 525
lower bound: 475-50= 425
Cp= (Upper bound-lower bound)/ 6σ
Cp= (525-525)/ (6× 50)
Cp= 0.33
Cpk is minimum of two following values: (Upper bound-mean)/ 3σ, (mean -lower bound)/ 3σ
Cpk in this case is: Min (0.33,0.33)
The Cp and Cpk values are calculated from the actual process values. Here target Cp and Cpk value is 0.33
