To understand this email requires reading the following link
www.maths.leeds.ac.uk/~charles/S1Jan08Q3.pdf
which is a scanned page from yesterday's maths A-level paper (Statistics 1).
(allstat does not allow attachments).
I am sending this as a follow-up to the discussion on "frequency density"
which appeared a few months ago on allstat, but anyone who teaches first
year students should find it of interest.
If you have any comments, or would like to submit your answer, please send it
to me and I will collate and circulate. However, for starters I offer the
following comment from an allstat colleague:
"Placing trick questions in an exam in inexcusable, and the
examiner and scrutineer (person who checked the paper) should
be sacked."
