4.6.5 Statistical hypothesis testing (A-level only)

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.
