Hi,

I am rubbish at maths, so I apologise for if this question is very simple...

I am trying to calculate whether a child is eligible for exam dispensation. To be eligible, it states that they must have 'an average, standardised score of 84 or less'.

I have tested speed of writing. A study of 2701 people found that the average writing speed for a child of his age is 17.8 words per minute (wpm). He wrote at a speed of 11.3wpm.

If I assume that there will be a normal distribution of the scores, is there a way of working out whether or not the child meets the criteria for exam dispensation (i.e. his standardised score is less than 84?)

Thanks
