Its not one sample. My statistics textbook tells me that I can apply the central limit theorem because I feel that a sample of 80 adequately represents the population of 40GB PS3s at large. The only issue is precisely how accurately he reported the information, so the real problem is not the representativeness of the sample but how accurately twesterm measured it. |
I had a good laugh. Applying a sample of 80 to gain insight into a population of approx. 14-15mill??? May I suggest you re-read that textbook again from cover to cover and then come back and realise what an absolute idiotic assertion that is.
At 99% confidence level the failure rate of all 40Gb PS3s is 10% +/- 8.65 based on twesterns data. ie - could be anything.
Thats even assuming sample data is random and even legit.
See what happens when Kiwis try to read???








Is there anything wrong with taking his personal experience as a strong indication of the reliability of the 40GB PS3? I haven't really seen any real source that beats it really.
