Question 31

The age ( $a\,$ years) and height ( $h\,$ metres) of 10 oak trees were measured.

The product moment correlation coefficient for this data set is $r = 0.750$ .

Stating your hypotheses clearly test, at the 1% significance level, whether there is a positive correlation between tree age and height.
