The temperature and the rainfall on 15 days is recorded.
Suggest a null and alternative hypothesis for a two tailed test to investigate whether there is a correlation between temperature and rainfall.
The product moment correlation coefficient is calculated to be r=0.37r = 0.37r=0.37.
Test your hypotheses at the 10% significance level.
