问题如下:
Which of the following statements regarding a one-tailed hypothesis test is correct?
选项:
A.The rejection region increases in size as the level of significance becomes smaller.
B.A one-tailed test more strongly reflects the beliefs of the researcher than a two tailed test.
C.The absolute value of the rejection point is larger than that of a two-tailed test at the same level of significance.
解释:
B is correct.
One-tailed tests in which the alternative is "greater than" or "less than" represent the beliefs of the researcher more firmly than a "not equal to" alternative hypothesis
absolute value of the rejection point 为啥我理解的是“拒绝点的绝对值”呢(即不考虑正负号)?怎么理解的就是那个点阿尔法对应的1.96/1.65呢
