Wtf is question 8 & 9 going on about?

Im not sure we need to know about a normal distribution curve for this module, its not in the specification, but otherwise, very good quiz

In AQA, normal distribution curves are in the specification. In chapter 7 variation, along with standard deviation.

And Elliot, if you read chapter 7 and look at normal distribution curves you will understand the percentages.

wow i actually got 100% in this. Good quiz especially questions 8 & 9. Havent been asked that question since GCSE!!

im sorry but if you do read the aqa book it does state that you will not be asked to calculate standard deviation in the exam so you dont need to actually know anything about it unless your doing coursework or studies on it :)
