In this question, I believe there is typo while obtaining confidence interval of T distribution. It is given T13,0.05/14 which is incorrect , it should be T13,0.025/14. Please clarify once.
This error was corrected in 2014. Hence you are using pre-2014 notes. Which means either you have been taking this exam for at least 3 years or you are using someone else's old notes and breaking the copyright agreement.
It's actually pretty easy to find pirated CT3 CMP with a google search. Just a heads up John, in case you want to try to stop Google showing that result.
Thanks Satya. I'll get a cease and desist order issued by the legal team. Obviously, I only give my time to help students who purchase our materials from us rather than steal them.
