The temperature and the number of hours of sunshine on 12 days is recorded.
The product moment correlation coefficient is calculated to be r=0.636r = 0.636r=0.636.
Stating your hypotheses clearly test, at the 1% significance level, whether there is a positive correlation between temperature and hours of sunshine
