Question 2
52%

The amount of rainfall (x x\,x mm) and the wind speed (y y\,y knots) were recorded for 15 days.

The product moment correlation coefficient for these data is calculated to be r=0.521r = 0.521r=0.521.

Stating your hypotheses clearly test, at the 5% significance level, whether there is a positive correlation between rainfall and wind speed.
