The sample PMCC satisfies [...]\text{[...]}[...].
A
The sample PMCC satisfies −1≤r≤1\boxed{-1\le r\le 1}−1≤r≤1.
B
At significance level α\alphaα, p≤α\boxed{p\le\alpha}p≤α means reject H0H_0H0.
C
When ∣r∣|r|∣r∣ exceeds the positive critical value.
D
Reject H0H_0H0, since −0.61<−0.55-0.61<-0.55−0.61<−0.55.
