Six Sigma:

Consider two processes A and B each with sample size of n = 5

Process A: Mean = 100    Sample Standard deviation = 3
Process B: Mean = 105     Sample Standard deviation =1

Specifications are 100 ± 10,

a. Calculate C_p and C_pk for each process and interpret these ratios

b. Which process should be preferred and why?
