(c) The Berenblutt-Webb test Statistic is
 
     g = (RSS_{1ST DIFFERENCE EQUATION}) / (RSS _{UNDIFFERENCED EQUATION})
       = (2.93*10⁹) / (2.22*10⁹)
       = 1.320

     For 41 observations, n = 41, k' = 1, and significance level = 5%; the significant Durbin-Waston
     statistic d_L is 1.45. Since the Berenblutt-Webb g statistic, 1.320, fall below d_L, do not reject the
     null hypothesis that p = 1.
