A research company patented two tests, Test A and Test B, that measure
various aspects of athletic performance. (We know that both these tests take
into account the maximum aerobic capacity measured by VO2.)These two tests
are standardized to have the same distribution with mean 50 and standard
deviation 25.A large group of athletes takes the first test, and of these,
the top 75\% are selected to take second test. Do you expect this select
group to perform (on average): a) better; b) worse; c) the same as they
performed on the first test?
Explain your answer.
我觉得Whether or not these two tests are standardized is irrelevant in this
problem， 并且在没有更多信息的情况下，应该判断select group to perform the
same as they performed on the first test, on average.
大家觉得我漏掉什么了吗？ |
