If the standard deviations are obtained to be 4N-m and 5 rpm for torque-165 N-m and rotational speed-3000 rpm through a large number of measurements,
(a) calculate the power of the engine. (b) Calculate the standard deviation of the power. (c) Calculate the random and systematic uncertainty of the power. (d) calculate the total uncertainty of each power measurement at a 95% confidence level.
