In a Reproducibility and Repeatability study, the following values have been obtained: variance by repeatability 0.04, variance by reproducibility 0.05, total variance 1.19. In this studio:

a. The variance of the parts is 0.09

b. The variance of the measurement system is 1.1

c. The contribution of the variance by the measurement system is 7.56%

d. It follows that it is necessary to improve the measurement system
