1)In Past paper April 2007 a)-Question 7 ,part iii How can we wirte ,P(s>2040)=P(N>4) b)-question 12,part(ii)c P-value lies between .40 &.30 [t(22)=.29] Why , take P-value <.8
I dont have that question in front of me but i remember the question. You model the number of prize certificates binomially and the 4 represents the number of prize certificates out of 200. For example to obtain £2040 you can have at least 4 prizes at £20 each and then remaining 196 at £10. This is where that comparison in (a) comes from. As the (b) i dont recall that question.
