Problem 4. Identifying the metal. A solid metallic sphere used in a particular machinery has a diameter of (1.256 + 0.003) cm and mass of (7.38 ± 0.04) g at room temperature. At this same temperature, zinc has a density of 7.14 g/cm3 with uncertainty that is less than 0.01 g/cm. Can you conclude (within two sigmas) that the metal is effectively made up of pure zinc? Justify your answer.
