问题如下:
Which of the following statements is correct with respect to the null hypothesis?
选项:
A.It can be stated as “not equal to” provided the alternative hypothesis is stated as “equal to.”
B.Along with the alternative hypothesis, it considers all possible values of the population parameter.
C.In a two-tailed test, it is rejected when evidence supports equality between the hypothesized value and the population parameter.
解释:
B is correct. The null hypothesis and the alternative hypothesis are complements of one another and together are exhaustive; that is, the null and alternative hypotheses combined consider all the possible values of the population parameter
原假设和备择假设互为补充,并且是全覆盖的; 也就是说,原假设和备择假设相结合考虑了总体参数的所有可能值。
hypothesized value and the population parameter这句话是什么意思,这两个值想不想等是怎么推出结果的?
