问题如下：
Determine using Exhibit 2 which one of the following statements is most likely to be correct. Monthly seasonality in the firm’s portfolio is________.
选项：
A.highly likely B.highly unlikely C.not able to be determined from the given data解释：
B is correct. Monthly seasonality in the firm’s portfolio is highly unlikely. Thevariance explained by the model (R-squared) is only 10.3%, and after adjusting forthe number of independent variables (adjusted R-squared), it becomes negative.Also, the insignificant F-statistic indicates a 56.3% chance that all variable coefficients are zero. Finally, t-statistics and associated p-values indicate that all thevariable coefficients are insignificant (i.e., not significantly different from zero).Consequently, monthly seasonality is highly unlikely to exist in this portfolio.
所以只要说significant F 就是 F的p value 就和significance level（e.g. 5%）比较就可以了？
