死人最少的車 == fewer than 22 driver death per million registered vehi

for Volvo, 2007 has < 500k cars sold (all models combined), 2008 < 400K sold. so probably not even qualified for statistically meaningful results.  as mentioned by -先想一想再說

所有跟帖： 

• 如果每半個Million的車在那幾年之內死了10個駕駛人，那麽數字就是20，還是有統計意義。 -TBz- ♂ (144 bytes) () 10/03/2013 postreply 21:29:53
