Biomedical Engineering > GATE 2022 > Measurement Uncertainty
Independent voltage measurements (μ±σ) of three sensors where μ and σ are the mean and standard deviation of the measurements, respectively are as follows: v1 = 4.52±0.02 V, v2 = 4.21±0.20 V, v3 = 3.96±0.15 V. The measurement uncertainty in v1 + v2 + v3 is _______ V (rounded off to two decimal places).
Correct : 0.25 to 0.26
