There are 24 positive integers in a sequence, the first 12 integers are less than 50 and the second 12 integers are greater than 50.
Quantity A: the median of the sequence
Quantity B: 50
选项
A、Quantity A is greater.
B、Quantity B is greater.
C、The two quantities are equal.
D、The relationship cannot be determined from the information given.
答案
D
解析
24个数的median显然是经过排序后的第12个数和第13个数的平均值;现在有12个数小于50,有12个数大于50;那么排序后第12个数必然小于50,第13个数必然大于50,但是由于不知道它们的具体数值,因此这两个数的平均值与50无法比较,所以选项D为正确答案。
