JITTER IN A WATER POWER SYSTEM. Refer to the Journal of Applied Physics investigation of throughput jitter in the opening switch of a prototype water power system, Exercise $6\mathrm{.}102.$ Recall that low throughput jitter is critical to successful waterline technology. An analysis of conduction time for a sample of $18$ trials of the prototype system yielded and $.($Conduction time is defined as the length of time required for the downstream current to equal $10\%$ of the upstream current.$)$ A system is considered to have low throughput jitter if the true conduction time standard deviation is less than $7$ nanoseconds. Does the prototype system satisfy this requirement? Test using $.$
