An irregular solid has a measured mass of 165.0 g ± 0.5 g. When submerged, it displaces 19.5 cm³ ± 0.2 cm³ of water. Tabulated densities (in g/cm³) for candidate materials are:
• Brass 8.4–8.7
• Bronze 8.7–8.9
• Nickel 8.9
Considering the measurement uncertainties, list all candidate materials that cannot be ruled out.
