网考网解析：
While at first glance it would seem that Data Set B would be greater, it is actually impossible to tell. If x is 10,000, for example, then Data Set A will clearly have a higher mean than Data Set B. On the other hand, if x is strongly negative— -10,000, for example—then Data Set B will definitely be the larger set. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
