    Sorry, I was on about the probability one, Im not sure of question numbers.
    For the confidence interval did you do it in thousands? Because it was for wages? Can you remember what you kinda got?

    And I agree.
    Don't even ask I was far off... i got something that didn't even lie in the conference interval

    I got something quite bizarre, like the two values that you have to evaluate didn't lie near mine at all

    yeah, the regression line question was alright for 5 marks.
    I think there were a few normal distribution questions, just looking up in tables which weren't too bad either.
    I really dont want to retake, I just dont know what grade Ill be happy with

    I thought it was a alright paper apart from part b of the twin questin where they have another brother involved, but I could figure it out after making lots of calculations. loool and the petrol question with 1.34 pound for each litre, i think you have to times both means and s.d. of the petrol by the prize for each litre. well we will see anyway.

    I messed up on the last question. I did the whole thing in thousands. As a result I will probably lose all 11/14 marks because statistics is like that.. I will probably re sit because I want to aim for 100 UMS in it.

    I think they'll accept it in thousands, the question clearly stated 'in thousands'

    They should give all the marks.

    I mean, I did the whole question in thousands... Therefore I got a different mean, standard deviation etc.. :/ Tbh, I'm going to re-sit it in the summer to see if I can score 95+ UMS

    I appreciate your hopefulness though.

    I messed up on 1 question too and got a B looking back it looks fairly straight forward which makes it worse, hopefully we can get an A this time!
