问题如下：
The most appropriate interpretation of the results reported in Exhibit 1 is that:选项：
A.the F-statistic of the regression is not significant. B.predictions of defective assemblies per hour made using the regression have only about a 41% chance of being correct. C.variations in the independent variables explain approximately 41% of the variation in the defective assemblies per hour.解释：
Solution C is correct. The R2 indicates that variations in the independent variables explain approximately 41% of the variation in the dependent variable. The F-statistic is highly significant. R2 does not inform us regarding the probability of a dependent variable prediction being correct.
A is incorrect. The F-test of the regression is highly significant.
B is incorrect. R2 does not inform us regarding the probability of a dependent variable prediction being correct.
解析说The F-test of the regression is highly significant，可是表格内写着significance of F 是零。这该怎么理解？
