问题 Quantity A: the standard deviation of 10, 45, 50, 55, 90
Quantity B: the standard deviation of 10, 30, 50, 70, 90
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 B
解析 两个数列的平均值都为50，相同数字是10，50，90；但是Quantity A中的45和55距离50比Quantity B中的30和70距离50要小，因此Quantity A比Quantity B小，选择B。
