1. Multisigma Corp. has a process they believe is operating near a six-sigma level and want to verify this. If the specification for a critical part in the process is 2.80 cm ` 0.10 and the standard deviation for the process is 0.0169, at what sigma level is this process operating?

2. NanosElectron, Inc. manufactures 75,000 circuit boards per month. A random sample of 800 boards is inspected every week for three characteristics. During a recent week, four defects were found for one characteristic, two defects were found for another characteristic, and one defect was found for the third characteristic. If these inspections pro- duced defect counts that were representative of the population, what is the overall sigma level for this process? What is the sigma level for the characteristic that showed four defects?

3. A flowchart for a hospital preadmission testing process is shown in Figure 9.25. Determine the important quality characteristics inherent in this process and suggest possible improvements.
