The range of the heights of the female students in a certain class is 13.2 inches, and the range of the heights of the male students in the class is 15.4 inches. Which of the following statements individually provide(s) sufficient additional information to determine the range of the heights of all the students in the class?
Indicate all such statements.
A The tallest male student in the class is 5.8 inches taller than the tallest female student in the class.
B The median height of the male students in the class is 1.1 inches greater than the median height of the female students in the class.
C The average (arithmetic mean) height of the male students in the class is 4.6 inches greater than the average height of the female students in the class.


个人感觉这个题目是没有正确答案的，答案A有个假设前提：女的最矮的是比男的最矮的要矮。可是这个假设前提题目中并没有说明啊。你们认为呢？

应该是这样的，既然female的range是13.2inch，male的是15.4inch，那么A中所说的就是最高的男的的身高比最高的女的身高高5.8，那么，最低的男的身高肯定要比最低的女的身高要高，这是推出来的，所以所有学生的身高的range应该就是最高的男的的身高减去最矮的女的身高~~~不知是否清楚。
