Model answers attached to the first post.

Q1. Standard correlation. I think the mark scheme will be very generous in part c)


Q2. DRV. Pretty easy if you revised cumulative distribution questions.


Q3. Regression. Fairly easy as it was obvious that t was x.


Q4. Normal distribution. Standard apart from c) I think that will cause a lot of problems.


I think part c) is very badly worded.




Q5. Measures of location/spread. Standard. The histogram part is very easy but always causes problems. Finding the probability using normal distribution is not going to be necessary.


Q6. DRV/Probability. Quite a confusing question, I think this will cause quite a few problems.


Q7. Venn. I thought this was pretty easy but I can see it causing a lot of problems.
