For question 4c), how many marks do you think I would lose as I left my answer as P(L>133) = 0.0139 - I didnt do the P(L>133|L>127) ???

For q5e, wouldnt it be 1-0.7019 which gives 0.2981, and then 0.7019 - 0.2981 = 0.4038?

What do you think the grade boundaries will be? 90%=A*, 80%=A etc? It looks like I've dropped 7 marks, so do you think that will be an A*?

I'm extremely gutted I didn't get the Alice phone question right because I divided the P (127 < x < 133) over P (x > 127) so I found the probability it would run out of charge during the five hour journey

other than that it looks ok though, thought it was quite a tough exam for a stats paper

I hope 90% is about 66 and 80% is 59

I may not have done as badly as I think I did, haha!

Ironically, I think I did the best on q7 and probability tended to be one of my weakest areas.

I didnt even draw a tree diagram but i think (or hope) that if u get the answer right then it doesnt matter.
