Based on the results and a 5% level of significance, which of the following hypotheses cannot be rejected?
选项
A.H_0 ∶ B_0=0
B.H_0 ∶ B_1=0
C.H_0 ∶ B_2=0
D.H_0 ∶ B_1=B_2=0
答案
B
解析
The t-statistics for the intercept and coefficient on Bi are significant as indicated by the associated p-values being less than 0.05: 0.0007 and 0.0004 respectively. Therefore, H_0: B_0=0 and H_0: B_2=0 can be rejected. The F-statistic on the ANOVA table has a p-value equal to 0.0012; thereforeH_0: B_1=B_2=0 can be rejected. The p-value for the coefficient on B1 is greater than five percent, therefore, H_0: B_1=0 cannot be rejected.Bi的截距和系数的t统计量很显着，如相关的p值分别小于0.05：0.0007和0.0004所示。 因此，可以拒绝H_0: B_0=0 和 H_0: B_2=0。 ANOVA表上的F统计量的p值等于0.0012； 因此，H_0: B_1=B_2=0可以被拒绝。 B1上系数的p值大于5％，因此H_0: B_1=0不能被拒绝。
