NO.PZ201512020300000402 问题如下 2.Whiof the following is Chiesa’s best response to Question 2 regarng sericorrelation in the error term? a 0.05 level of significance, the test for sericorrelation incates ththere is: A.no sericorrelation in the error term. B.positive sericorrelation in the error term. C.negative sericorrelation in the error term. B is correct.The rbin–Watson test useto test for sericorrelation in the error term, anits value reportein Exhibit 1 is 1.65. For no sericorrelation, is approximately equto 2. If 1 , the error terms are positively serially correlate Because the = 1.65 is less th=1.8271=1.827=1.827 for n = 431 (see Exhibit 2), Chiesa shoulrejethe null hypothesis of no sericorrelation anconclu ththere is evinof positive sericorrelation among the error terms. =1.65，小于表2中的任何数，难道不应该落在接受域中吗？不应该接受H0吗

问下，这里查表，N是代表observation的个数＝431吧？然后用N＝430近似替代吗？
