OCR S2 (non-mei)

It asked for u and sigma

For the doctor question, did you all reject H0? I got mean 11.76, variance 18 (unbiased estimator) and a z value of 1.92 or something like that

So the answers were:

u=146 and sigma=2, right?

So the answers were:

u=146 and sigma=2, right?

yep i edited my post saying Var=4, hope i didnt worry too many people i just forgot what the question was

What did everyone get as the value for a for each part of the questions? I got a=6 for both....

What did everyone get for 7ii)? Most people I've talked to either put 37 or 38.

I stored all my answers in my calculator and here they are (I think 8ii is wrong):
1. Mean = 146, sigma = 2
2. i) The rabbits occur independent of each other
ii) 0.222 (Using poisson)
3. i) a = 6
ii) a = 1.5
4. 0.8311
5. 0.2536
6. 0.9807
7. i) 0.1247
ii) 38
8. i) 0.0316
ii) 0.961 (I did 1 - (1/3((1-0.9685)+(1-0.6047)+(1-0.0933)))^4)

38

It's 38, I didn't know which way to round so I carried out the test on 37, 38 and 39 and 39 is the first one you do not reject.

I got 37, you need to round down. I remember testing the different values and 38 didn't fall in the critical region

I did the test for 38 and got that you do not reject it. Did you remember continuity correction?
