The amount of daily rainfall and the maximum wind speed recorded on 15 randomly selected days in a coastal town yielded a product moment correlation coefficient of r=0.525r = 0.525r=0.525.
Stating your hypotheses clearly test, at the 5% significance level, whether there is evidence of a positive correlation between daily rainfall and maximum wind speed.
