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=0.720r = 0.720r=0.720.
Stating your hypotheses clearly test, at the 1% significance level, whether there is a positive correlation between Mathematics scores and Physics scores.
Practise Edexcel A Level Maths Hypothesis Testing for Zero Correlation with exam-style questions for A Level Maths. 52 questions, matched to the Edexcel A Level Maths (9MA0) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
