Uncertainty can be estimated only after the instrument is acquired and testeden uncertainty is can be done in the design stage) No Question 14 0 We are interested in calculating the density of air from measurements of pressure and temperature. During uncertainty analysis we are likely to preform (Choose best answer only.. A) Error combination only B) Error propagation only . Both error propagation and combination D) Ure the density directly E) This cannot be done as we did not measure the density
The root sum square rule (RSS) discussed in uncertainty analysis is mainly used: a) To find the root mean square of a signal b) To combine the effects of independent errors c) To determine the exact variance of a measurement d) Only along with error propagation e) For none of the above Question 16 If a system has high precision, this means that: a) It has high random error b) It has high accuracy error c) Both of the above d) None of the above
The following are common instrument error types EXCEPT a) Hysteresis error b) Linearity error c) Zero error d) Sensitivity error e) Human error Question 18 Hysteresis (in a measurement instrument) is the dependence of the indicated value on the direction of a sequential test. Yes No
