A load cell is used to take repeated measurements of the force produced by a hydraulic cylinder. The load cell has an operating range of 0 to 310 Newtons, and an accuracy of 0.16% of full scale span. 5 measurements made over time under fixed operating conditions are 120.1, 122.6, 121.9, 120.8, 121.4 Newtons. Determine the Nth order uncertainty (at 95% probability) of true force output.
