Hmm, with the general consensus being 37/38, I don't see it being 41. Are you sure those are the correct values for n and p?
Yes, I used the poison approximation and got 37. I can't see a flaw with either methods so I'm kind of scratching my head as to which is correct. Part of me says that they're both not incorrect but since they're approximations then it explains the difference between the two answers

I got 37 too, so I think for the sake of our own sanity it's best that we assume our answer is correct
To clarify, for the 11 marker, you estimated the population variance from the data given to get the population variance was 18, then you divided 18 by 120 to estimate the sample variance?
Here are the answers I got: 1. Mean=146 ans sd=2 2i. Something along the lines that the occurrence od dead rabbits is unpredictable and don't occur at a certain pattern 2ii. Dead rabbits occur independently. In other words, the appearance of one dead rabbit doesn't influence the death of another one 2iii 0.222 (3sf) 3i. 6 3ii 3/2 3iii x represent the values that X can take 4. Missed question 4 out 5. I think accepted h0 I cant remember 6i. Accepted h1 (I think its the one about the dentist or something 6ii. It is necessary to assume normal distribution since the variable t's parent distribution wasn't mentioned. CLT can be used since n is very large 7i. 0.125 7ii. 37 8i 3.15% 8ii. 0.961 judging by other answers I think I got it wrong since I calculated p=3. Bright side is I used binomial distribution
