Jitter is a term used to describe the variation in conduction time of a water power system. Low throughput jitter is critical to successful waterline technology. An investigation of throughput jitter in the opening switch of a prototype system yielded the following descriptive statistics on conduction time for 18 trials: -334.8 nanoseconds and s = 6.3 nanoseconds. (Conduction time is defined as the length of time required for the downstream current to equal 10% of the upstream current.) a) Construct a 95% confidence interval for the true standard deviation of conduction times of the prototype system. b) A system is considered to have low throughput jitter if the true standard deviation of conduction times is less than 7 nanoseconds. Does the prototype system satisfy this requirement? Use a=0.01.

Question
Jitter is a term used to describe the variation in conduction time of a water power system. Low
throughput jitter is eritical to successful waterline technology. An investigation of throughput
jitter in the opening switch of a prototype system yielded the following descriptive statistics on
conduction time for 18 trials: =334.8 nanoseconds and s = 6.3 nanoseconds. (Conduction time
is defined as the length of time required for the downstream current to equal 10% of the
upstream current.)
a) Construct a 95% confidence interval for the true standard deviation of conduction times
of the prototype system.
b) A system is considered to have low throughput jitter if the true standard deviation of
conduction times is less than 7 nanoseconds. Does the prototype system satisfy this
requirement? Use a = 0.01.
