A recent report determined that although only 3 percent of drivers on Maryland highways equipped their vehicles with rader detectors,33 percent of all vehicles ticketed for exceeding the speed limit were equipped with them.Clearly,drivers who equip their vehicles with rader detectors are more likely to exceed the speed limit regularly than are drivers who do not.
The conclusion drawn above depends on which of the following assumptions?
答案是 Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed. 为嘛啊为嘛啊为嘛啊?看了答案也不理解!!!求大神解释!!!! |
