This paper is the second one (Part II) in a series of two papers (Part I and Part II) designated to provide practitioner’s perspective on the GUM revision. Part I has discussed two key problems and their solutions. This paper (Part II) examines four examples of the GUM in detail, using the two alternative approaches described in Part I to calculate the expanded uncertainty, and compares to GUM’s WS-t approach. It also describes the resolutions to the Ballico paradox due to GUM’s WS-t approach.
