In tests for pironoma, a serious disease, a false positive result indicates that people have pironoma when, in fact, they do not; a false negative result indicates that people do not have pironoma when, in fact, they do. To detect pironoma most accurately, physicians should use the laboratory test that has the lowest proportion of false positive results. Which of the following, if true, gives the most support to the recommendation above? 这个么楼主~~~~~~ -- by 会员 ielaine0828 (2012/12/20 11:13:42)
病是不是这个病我忘了,但考的这个古从In tests for pironoma, a serious disease, a false positive result indicates that people have pironoma when, in fact, they do not; a false negative result indicates that people do not have pironoma when, in fact, they do.到这里,意思都是对的,可能叙述的不太一样,但后面的不一样~也是考一个人被检查出有病,然后怎么怎么的,真忘了,最后考削弱。。。(我主要是一开那个positive和negative以为是考古呢,就也没太特意记是什么意思。。所以后半部分不记得了。。。) |
