问题如下：
The results reported in Exhibit are most accurately
interpreted as indicating that:
选项：
A.
multicollinearity is not present.
B.
the reported R2 is spurious.
C.
the regression coefficients have inflated standard
errors.
解释：
The pairwise correlation is low. The only case in
which correlation between independent variables may be a reasonable indicator
of multicollinearity occurs in a regression with exactly two independent
variables, as is the case in this problem. Furthermore, the additional classic
symptoms of multicollinearity (high R2and significant F-statistic
but not significant coefficients) are not present.
请用中文说一下判断标准。
