The sample correlation coefficient satisfies [...]\text{[...]}[...].
A
When ∣r∣≥c\lvert r\rvert\ge c∣r∣≥c.
B
Assuming H0H_0H0 is true, the p-value is the probability of a result at least as extreme as the observed result.
C
The sample correlation coefficient satisfies −1≤r≤1\boxed{-1\le r\le1}−1≤r≤1.
D
A negative linear correlation.
