可以直接用f=t^2吗

问题如下：

10. Based on Liu’s regression results in Exhibit 2, the F-statistic for testing whether the slope coefficient is equal to zero is closest to:

选项：

−2.2219.

3.5036.

4.9367.

解释：

C is correct

because $F=\frac{Mean\text{regression sum of squares}}{mean\text{squared error}}=\frac{38.4404}{7.7867}=4.9367$
