It's hard to see that when it is computerized. I believe we are right! If not, it's one mark maximum, but we're probably right. I remember reading it in my textbook like 10 minutes before the exam and my maths teacher said:
I'm really not sure about this.
I also didn't drew less than 10.0 for a zero. Started with 10-10.5. Not sure if a mark will be deducted for that too.
Q1 [4 marks]
(iii) 200 samples are taken. Find the probability between 163 and 173 inclusive
np=160 npq=32
Less than 173.5: 0.9915
Less than 162.5: 0.6707
Between them= 0.321
Ans: (i) 0.653 (ii) 0.561 (iii) 0.321
Feel free to post any queries or mistakes
I did exactly the same thing!!! High-five brooo. Team NotTooSureAboutHistogramBoundaries will take over Xtremepapers! lol
Have a look at the last question, last part of this paper.
What else did you get wrong?
no thats okay. you wont loose a mark dude.
you will get high Ano thats okay. you wont loose a mark dude.
Well I am getting 42 max in S1, 67 max in P1, 58 max in P3 and 40 max in M1.
So overall not an A* and maybe not even an A. You're better off than me man!
Hey! The boundaries for A* have gone as low 205 or even less if I'm not mistaken and this year P1 was hard and P3 and M1 were harder from what I've heard. So you surely have a chance!no thats okay. you wont loose a mark dude.
Well I am getting 42 max in S1, 67 max in P1, 58 max in P3 and 40 max in M1.
So overall not an A* and maybe not even an A. You're better off than me man!
And I'm getting exactly the same variance but a different mean for the mid-points you used!no thats okay. you wont loose a mark dude.

I think that my S1 and M1 marks can go as low as 37. Plus the highest A has ever gone to was at 197 so that is very dangerous for me man!
A* has jumped upto 223 as well, so who knows? I'd want to commit suicide if I get a B. I cant handle it.
well just relax and hope that everything goes well
It has gone as above as 230 I think
but don't worry! It will nowhere be that high this time as all papers were difficult except S1.I made the silliest mistake on the permutations question for 5p2. I multiplied it by 5 instead of 3 (so many 5s made me write it even though I knew I had to multiply by 3, didn't even notice). Also taking off marks which I have not identified as error,s, you know, we all have those small mistakes we think are correct and are only worth 1 mark, such as rounding to wrong amount of s.f.'s, so I'm deducting marks off myself to get in the worst case. If that makes any sense lol.
All the answers here.Hello guyz as its been 24 hours lets discusss......
so i hve given variant 62 for statistics...!!!
first q was it 0.813 i guess
wat was de standard deviation in the last q first part??
what mean nd variance u got?? nd what was the frequency density for <10.0 ??
thanks man! Well we can prayIt has gone as above as 230 I think
