A part diameter specification is 115.00 mm /- 0.30 mm. This part is measured with a Vernier caliper. What is the required resolution of the Vernier caliper, using the process variation method, if this process is running at a 5.0 sigma level process? Assume the process is centered between the specification limits. Please write your answer with 2 decimal places and no units (for example: 0.12)
