Advance info for this doesnt really give much away, what do we think will come up?

I mean the only particularly revealing bullet point is the chi squared one - which specifies that it's a binomial one
Guys, what about the power of the test, didn’t see they mention that

the final bullet point is type 1 and type 2 errors, so there will be a question on quality of tests

that and the hypothesis testing probably 2 of my weakest part.
Anyone knows whether can I use the calculator for the Central Limit theorem, will I lose 1 method mark there without standardised it although I get the correct answer?

depends how harsh the mark schemes are - i usually write down each stage of my working even if i'm just plugging everything into my calculator

On the mark schemes I've seen (and even the ones on the topic tests they gave), they give both methods, so it's your call (although I'm sure Edexcel realises the increasing use of calculators). I personally just do it on the calculator. Unless you need to find a variable within the distribution where you kinda have to standardise it
How did the exam go?
Anyone knows is the binomial question about the cubs is rejected or accepted?
And what you guys get for the P(X^2<1-2X)

I got 0.35 for that P(X^2<1-2x) one and I can't remember the cubs ome
What did people get for n and C on the last one

0.35 also, the cub one I rejected, I just worry bc I get the Test Statistic quite high due to there is 3,75 in the middle so I combined cells. U guys only combine 2 and 3 or combining all 2,3,4?

Oh yeah I got rejected because it was greater than

Did you do P(X=0) + P(X=-1)?

Wasn’t it 37.5?
Original post by grhas98
Did you do P(X=0) + P(X=-1)?

Yeah, I put both of them into a table and compare
Anyone get n=8

Cool just checking because I can’t remember my answer lol
