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 thought it said B OR NOT C how many marks would i lose? And for regression i got my variables wrong so subbed them in wrong etc how many marks would i lose out of 5
