They recently installed new system software which they hope will meet servicespecification limits of 3 -7minutes and have a Capability Index (Cpk) of at least 1.2. They want to also design a control chart for bank teller use. They have done some sampling recently (sample size of 4 customers) and determined that the process mean has shifted to 5.2 with a Sigma (standard deviation) of 1.0 minute.

  1. compute for Cp and Cpk values:
  2. compute for mean, UCL and LCL
