Question 41

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

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

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