Problem

A group of students measure

I_{\text{in}}=1.24\,\text{A}\pm0.03\,\text{A}

entering a junction and

I_{\text{out}}=1.18\,\text{A}\pm0.04\,\text{A}

leaving it. Decide whether their data confirm Kirchhoff’s junction rule. State "confirmed" or "not confirmed" and justify your answer with a brief uncertainty comparison.
