Consider the following values of elemental random errors in its calibration: (S)=0.7 N/m² and v₁ = 41 (S)=1.70 N/m² and v₁ = 20 (S)=0.12 N/m² and v₁ = 30 Calculate the random standard uncertainty due to calibration errors with its degree of freedom. (a) ±1.424 N/m² and 23.15 (b) ±1.424 N/m² and 27.18 (c) ±1.84 N/m² and 23.15 (d) ±1.84 N/m and 27.18
