An ensemble member of a stationary random process X(t) is sampled at Ntimes t₁, i = 1, 2, ..., N. By treating the samples as random variables X; =X(t), an estimate or measurement й of the mean value Xprocess is sometimes formed by averaging the samples:= E[X(t)] of the For the random process and samples defined in Problem 8 let an estimateof the variance of the process be defined by=-1 NNΣ (Χ, - 82Show that the mean value of this estimate isN-1E[0]στN
