问题:

有些顾客抱怨到某银行办理业务时,等待的时间太长,管理员认为可能由于排队方式不合理,造成少数顾客等待时间太长,为此,某银行采取两种排队方式进行实验,方式1是所有顾客都排成一个队列,按顺序办理业务,方式2是顾客分别在不同窗口办理业务,于是各随机抽取10名顾客,记录他们的等待时间(单位:分)如表1所示。表1若平均等待时间相差较大,就采用平均等待时间较短的排队方式,若相差不大,可能由于排队方式不合理使少数顾客等待时间过长,就会选择更合理的排队方式。

A.中位数相等,平均数不等

B.平均数相等,众数不等

     There was once a professor of medicine, who was very strict with the students. Whenever

he took the chair on the exam committee(担任考试委员会 * * ), the students would be in

fear, because he was seldom pleased with the answers they gave. A student would be lucky

enough if he or she could receive a good mark from him. At the end of the term, the students

of medicine would take their exam again. Now a student entered the exam room and got

seated before the committee. This student was a little nervous as he knew it would not be so

easy to get through the exam at all.

     The professor began to ask. The student was required to describe a certain illness, his

description of which turned to be OK.

     Then the professor asked about the cure for illness, and the student, too, answered just

as right.

     "Good," said the professor, "and how much will you give the patient?"

     "A full spoon", answered the student.

     "Now you may go out and wait for what you can get.", said the professor. At the same

time, the committee discussed carefully the answers the student had given. Suddenly the

student noticed that there was something wrong with his last answer. " A full spoon is too

much," he thought to himself. Anxiously he opened the door of the room and cried, "Mr

Professor, I've make a mistake! A full spoon is too much for a patient.He can take only

five drops."
