Reply #139: Calling it 'guessimation' is spin, and rather insulting to the statisticians

No, there are no 'contradictions' there:

"smoking causes 9 out of 10 cases" ~90%
"It (radon) may cause almost 1 in 10 lung cancer cases" ~9%
"as many as 1 in 10 lung cancers might be caused by air pollution in the Swedish capital, Stockholm" (ie one city, where we don't know how many people smoke, or if there's any radon gas, and so the rate there cannot be used for the developed world as a whole)
"Another research paper put the figure at about 1 or 2 lung cancer cases in every 100" 1-2%

total: 100-101%. It's nothing more than a rounding artifact.
