In logging data with a high sampling rate, the calculated standard deviation of large number of readings are 4.00 V, 1.00 A, and 0.02 for the power factor, while the mean values are 480 V, 50.0 A, and a power factor of 0.83. Determine the random uncertainty of the measurements, at a 95% confidence level.
