Perform the DurbinWatson test at the 5% significance level todetermine whether positive first-order autocorrelation exists whend = 1.10 n = 25 and k = 3. Test the following hypotheses with =.05. Ho: There is no first order autocorrelation H1: there ispositive n = 50 k = 2 d = 1.38 Plot the following time series todetermine which of the trend models appears to fit better.
