Nah. Im freaked out. p4 and p6. This is one pressure weekman ure a robot i guess
I love these questions. They are the easiest, that's why.View attachment 10562
and this? sory if I keep asking haha..
well just want to know how to do the 5(i)..
Ahh... thankss..that wierd symbol. ϕ is the fi. the function through which u have to go to the table
Well that's a surprising question. Student, though.Ahh... thankss..
will get back to u with more problems..
are u a teacher or a student?
thanksyou're looking for a number 'n', where 5000 < n < 6000 [or more precisely, the smallest and the largest number you can possibly achieve is 5123 and 5643 respectively] .. can't ever start with 6, can it?
Well. It depends on the intervals in the group data. If an Upper Boundary of the Interval is the same value as the Lower Boundary of the next interval, then there's no need to add/subtract .5 to the corresponding boundaries. I.e,Hye guys,i have a question,I have came across some histograms and i have no idea which one is a correct one. Why some histograms their class boundary are in decimals(0.5) while some are in round numbers? I mean when you draw it,some draw from the 0.5 while some draw on round numbers?
then its probability is 0.94?I love these questions. They are the easiest, that's why.
Within 12 g implies the least is 20-12 = 8 and highest = 20+12 =32
so P(8<X<32)
P( 8-20 / σ <Z< 32-20 / σ)
P(-12/σ <Z < 12/σ)
Seems familiar?
its like where you have continuous boundaries like 0<t<20,20<t<40 and so on then u dont have subtract .5 but if the boundaries are like 10<t<30 , 31<t<40 then ul have to subtract .5 and make it like 9.5<t<30.5 ,30.5<t<40.5 and so onHye guys,i have a question,I have came across some histograms and i have no idea which one is a correct one. Why some histograms their class boundary are in decimals(0.5) while some are in round numbers? I mean when you draw it,some draw from the 0.5 while some draw on round numbers?
yes.then its probability is 0.94?
im not able to solve Q2...help !
http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_w11_qp_61.pdf
and also i hv seen similar questions in many years recently,can some one tell me how to go about it ?
Hahah... just figured u know so much there's a good chance u might be a teacher..Well that's a surprising question. Student, though.
alright here you goim not able to solve Q2...help !

and also i hv seen similar questions in many years recently,can some one tell me how to go about it ?
is there any book or site where i can get the concept of this formula ? thanks,by the wayMean= Σ(x − a)/n +a
where a is a constant
Variance Σ(x − 25)^2 / n - [mean]^2
i didnt get it right... in MS how in the world did they get Z=1.882..yes.
hey check this question out.. in part 2 u do 4!/2! right? how to solve part 1 using this factorial method? it gets me confused when to use the factorials and when to use nPr.. :/Well that's a surprising question. Student, though.
I am not so sure, :/ do u Live in Khobar/Dammam?is there any book or site where i can get the concept of this formula ? thanks,by the way
