Question 37

The scores of 10 students in a Mathematics exam and a Physics exam are compared. The product moment correlation coefficient is found to be $r = 0.720$ .

Stating your hypotheses clearly test, at the 1% significance level, whether there is a positive correlation between Mathematics scores and Physics scores.
