Ended up firming QM instead =/ I'm relying highly on adjustment as it stands, which is never a good thing! KCL will be one place I'll ring first on results day(god knows if they will have availability though)
QM is not bad for maths. My sister went their for English. So if you need to ask questions about the area around the uni etc just pm me.
Is it like this.. VarXˉ=Var[nX1+X2+.....+Xn] =n21Var[X1+X2+....+Xn] =n21nVar[X] =n21∗n∗np(1−p) =p(1−p)
OR simply np(1-p)
In S4 new textbook page 24 example 15 in yellow box on right side, it says Var(X bar)=np(1-p) but in exercise 6F question 6 part b) they clearly dint use np(1-p) to estimate Var(X bar).

You are correct - they have made a slight mistake on the side of the example. They meant to say E(X)=np Var(X)=np(1-p). Note that the result you obtained above is consistent with the central limit theorem: [br]nσ2=nnp(1−p)[br]
In 2007 June paper question 6 part a) why didn't they use student's t-dist to find critical region but normal distribution instead???
n=15 isn't large sample size...
in order to carry out the t test, the population standard deviation must be unknown. You are given the distribution parameters in the question i.e. population standard deviation is known i.e. use z test.
IM DOING OKAY BUT MY COCK HURTS COS I SUCKED IT TOO MUCH LOL I'm joking
confidence intervals are a pain in the ass do we have to remember how to do them off by heart ? ? ?
Yh me too, i'm trying to calculate the variable length of my cock using a first order differentiational equation, but my calculator isn't strong enough to calculate numbers that large. Also i think that you can take your text book into the S4 exam. i read online that if you do it and lie to your teacher and say its allowed theyll let you. So **** revision. Im going to go take a nap, herpederpderp

HAHAHAHAHA I LIKE, I LIKE Um..a quick S4 question for you faggots:
10 independent samples of the length of my (hard) cock, in inches, were taken and the following results were obtained: mean = 150.29, s^2 = 0.0000000000001283
Test, at the 1% significance level, whether or not my cock can impregnate anshul95. State your hypotheses clearly, and please do not cover the paper in your cum because you jizzed at the size of my cock.

Hmm there is a flaw in your equations, you havent taken account of the fact that anshul95 is a one legged hermaphrodite which probably complicates it a little. I think you need to increase the variance of your hypothesis to reach a more chi squared value. of course you could always f test the recursion formulae but then the paired t-test would required a pooled estimate of the variance.
