# Statistics mark scheme watch

1. For this question I’m not sure whether I would get full marks or not, as I got the answer right but used my graphical calculator to get the answer. I have attached a photo of my working, the question and mark scheme. it is question 8(ii)

For the new spec this would be fine but you're doing a modular spec past paper so I assume you're doing the modular spec?

I have a feeling that you can't use these calculator functions in old spec statistics (apart from using them to check your answer) and you have to do the working assuming you don't have these functions i.e. you need to use the cumulative binomial tables.

I'm really not sure though because I know very little about modular spec stats. Muttley79 do you know?
3. Hi - as there are three marks I would think you need to show the use of tables. I've not met this issue before with someone using a graphic calculator to do it.

The use of graphing calculators is not permitted in the actual examination so you need to do it from the tables so ensure you get maximum marks.

Never use a graphing calculator or anything with algebraic manipulation as this will make you lazy and may slow you down in the examination.

Sorry, this is incorrect - you can use a graphic calculator just not one with algebraic manipulation. They do not 'make you slow' they are a brilliant aid and I say that as someone who teaches the subject.
6. I’m actually on old spec, and yes they do make you slow in terms of me assuming he was on old spec. Like with the derivatives button and integrals etc it’s just not maths anymore it’s just shoving numbers in a calculator. So as somebody who is a student, you are incorrect and I say that as student🙄.

Which calculator function did you actually use out of interest?

This is how I worked it out on my calculator
