Question 20

A glaciologist is investigating the linear relationship between the temperature of the ice, $T$ , and the concentration of a trapped gas, $G$ . Four different models suggest the following potential values for the product moment correlation coefficient, $r$ , for their dataset:

$\sin(4)$
$\ln(0.5)$
$\frac{\pi}{3}$
$\sqrt{2} - 2$

Which of the following is not a possible value for $r$ ?
