I am taking it....unforunately

Yay, A FRIEND!

Jokes, are you not liking it either?

I find it really frustrating for maths. Pure is so much better. Stats is just number crunching boredom. Wish I could have dine mechanics -_-

After the mess that was C3 today, I'm really hoping I do well in stats...
Does anyone have the june 2011 paper

ohh and *subscribed*

I like Venn Diagrams

I know what you mean but the Core 3 exam on friday was SOLID!

I am taking it....unforunately

I don't, but good luck!



I dislike only one thing more...


Love solid maths makes me weep tears of joy!

Oh the purity.

The perfection (nerdgasm)




Good luck!






By the way, does anybody know with Hypothesis testing, what is the X~B(29638) thing we need to put at the top? And when do we do it with Binomial testing?

L

The proportion of posts by trolls has been 20% in the past. A researcher believes it has increased; he takes a sample of 18 posts and finds that 7 are by trolls...
X~ Bin( 18, 0.2 )
Look up p( X >= 7 )
If it exceeds 5% accept H_o

I am.

Good luck!

I'm guessing people dnnt like stats. It's a shame, I think it could be a good subject, but for some reason it's never taught well

You too!

I think I don't like it because I'm doing it as part of AS Further Maths that I took up with my A2s, so I kind of focused more on my Core 3. Now I'm panicky

Don't worry,

I had Biology and Chemistry last week so I focused more on them. I'm now getting mixed high results so it should be ok. My tip is to be as focused as possible and carefully follow tye probabilities as there can be littlentrips

not too bad....how did you work out P(TnM)? did you get 0.264?

And a whole page to write a conclusion to that hypothesis test... How generous!
