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 + or -10,

  1. Find the process standard deviations
  2. Calculate Cp and Cpk for each process and interpret these ratios
  3. Find the percentage of production outside the specification limits
  4. Which process would you prefer?
