Edexcel S1 - 15th June, 2016 [Exam Discussion]

That wasn't the very last question, it was question 5 I think. It was worth 3 marks, the one where you explain if Shyan was justified in using a normal distribution.

Do we have an unofficial markscheme yet?

He's asking how much the last question AND the question you just mentioned are worth. Not just that one

basically guys for the diner question i got 17 people, is this correct and if not what was it and why?
cheers

I got 17 aswell but I'm not sure if its right

Was that the probability question with the hotel and stuff.
I got 33 because I did:
P(DIBnR)*number of people + P(DIB'nR)*number of people
9/20*40 + 15/37*37 = 18+15 = 33

Thank you. Think I did fairly well. Probably dropped about 10 marks max.
Do you know how many marks 90 UMS was last year?

oh **** i worked those two out in the previous question, pissed of now.

shot in the dark: 68

66 for 90 UMS so probably about the same this year or maybe even 65

I think I got 62 marks, what grade do you think it is? I flopped badly in this exam, because I missed a question accidentally

On that question when you have to say how the new data piece will effect the mean and Standard Deviation, will i get marks for just putting;

The mean will stay the same

The standard deviation will decreases

Thanks in advance

71/75. Any UMS predictions for me? @Zacken or anyone!

(PS: What would 73/75 on C1, 75/75 on C2, and 71/75 on S1 roughly be as an overall UMS?)

Thanks, and best of luck I hope you all achieve the grades you want!

Your probably looking almost at the full 300 UMS Marks Mate,

C1 - 98

C2 - 100

S1 - 97/98

Worst case scenario, 295 UMS
