In a measurement process carried out in 3 consecutive steps, the individual uncertainties at each step are given in the table below. Calculate the overall uncertainty in the measurement at 95% confidence level. (Note: The systematic uncertainties in the table are given at 68% confidence level). Please give sufficient explanations for each step of your calculation Systematic uncert. [unit] Random uncert.
