T/F The expected value of a random walk is dependent on time. Note: Make sure you understand what a random walk is! Think of the drunken man. - False. X_t = X_(t-1) + W_t, where W_t ~ Normal(0,V). T/F A moving average process is a linear process. - True. T/F If X_t is a stationary time series, then -Xt must be a non-stationary time series. - False. Taking the negative of the series does nothing to affect trend, variance, or add autocorrelation, and thus the process remains stationary. T/F...

What is the Mean, Mode & Median for the data in Column 1, Data Set A? a. Mean = 8.7, Mode = 8, Median = 7 b. Mean = 8.7, Mode = 7, Median = 8 c. Mean = 8, Mode = 8.7, Median = 7 d. Mean = 7, Mode = 7, Median = 8.7 e. Mean = 8, Mode = 8, Median = 7 - Answer B Formula: Mean = Sum(x)/n = 8.7 Mode = Most frequent value = 7 Median = because sample is even (n=50), the median is the average of the (n/2)th and ((n/2)+1)th values in the sorted series = 8 Please reference Quantifying Process Va...
