标题: [问题] 这句英文是否是专业的统计?
时间: Mon May 28 21:44:29 2012
"Rates of congenital malformations (among those exposed to the environment at
Love Canal) were twice that expected compared to the external standard
populations, a difference that exceeded the range of rates expected by chance
alone"
不好意思 最近在做关于污染的报告 在WIKI上看到这段话
不是非常的明白，个人猜测是否和专精的统计知识有关
所以到贵版 希望有人相助
如果有违反版规 有请版主删文
谢谢。
