问题如下：
Based on Exhibits 1 and 2, the correlation between the debt ratio and the short interest ratio is closest to:
选项：
A.
-0.3054
B.
0.0933
C.
0.3054
解释：
In simple regression, the R2 is the square
of the pairwise correlation. Because the slope coefficient is negative, the
correlation is the negative of the square root of 0.0933, or −0.3054.
slope coffecient是负的 是怎么看出来的

Because the slope coefficient is negative, thecorrelation is the negative of the square root of 0.0933, or −0.3054. 请问R的平方和correlation之间有啥关系呢？R的平方不是Coefficient termination？这个知识点有点混淆
