Below are some statistical statements. Can you decide whether each is always, sometimes, or never true?
If they are sometimes true, give examples or conditions under which they are true and under which they are false.
If they are always true or never true, give convincing reasons why that is the case.
Be sure to be clear about your statistical assumptions in each case.
Could you adapt any of the statements that are sometimes true to make them always or never true?
