There is a question in my Kaplan exam kit (this book is quite old from sep2016-aug 2017). the question number is 207. I’ve checked the answer and I still don’t understand how they’ve worked it out. could you please explain this to me?
I am sorry but I do not have the Kaplan exam kit and so I cannot help you on this question.
All of the statistical techniques relevant to Paper MA are covered in my free lectures. Also, I think it better if you buy a new edition of the Revision Kit because there have been a few statistical techniques added to the syllabus this year.
