Yeah but always is when it comes to the actual exam I think. Checking answers constantly and that.

Yep, n = 43.xxxx so minimum value was 44.

I feel you, lost 3 marks on the last question because I am the guy who is incapable of inputting values into a calculator.

Why hello there
11. for the last question were we meant to change the percentage values of the mean and standard dev into decimals? like 19.5% into 0.195?

I believe it wouldn't matter, as long as you were consistent
14. That's what I got
15. What did you guys put for the second last part of the Q I said Paul or whoever needs to ask the restaurant to investigate as 20%(what they claimed) is above the upper confidence limit.

44 for the last one

I think anything along the lines of 'lower the stated fat content' would be fine as long as you backed it up with 'outside 95% confidence interval'. As for the 44 that is what I, and a few others on the forum also go, almost certainly correct!
17. why 44? i got 27. anyone remember what the question was?

Thanks also Did you get the doctors claim was supported by data,

B(4,0.3) was suitable
Poisson dist was not suitable

For SRCC Sunglasses and ice-cream positively correlated
Whereas PMCC suggests it not positively correlated
For the last part of that Q Non-linear positive correlation
19. 2, 5.61
3 rs= 0.75
4, a) .7784 b).0107
5 1.95
Unbias mean 26.5, variance 12.7
The mean of the poisson is something like 1.8 and chi square for binomial is something 14.xx ?
Last question n=44
As long as i remember this is what i did
