可以麻烦老师解释下A选项吗 谢谢 解释：
NO.PZ2018062016000146 问题如下 Whiof the following statements on a non-parametric test is least accurate? A.It makes maximassumptions about the population. B.The sample ta cgiven in ranks. C.The hypothesis esn't concern a parameter. A is correct. A non-parametric test is a test this not concernewith a parameter, or a test thmakes minimassumptions about the population from whithe sample comes. There are three situations in this proceres: when the ta we use not meet stributionassumptions, when the ta are given in ranks, or when the hypothesis we are aressing es not concern a parameter. c为什么不正确呀，不涉及参数不是应该就使用非参数检验吗？

There are three situations in this proceres: when the ta we use not meet stributionassumptions, when the ta are given in ranks, or when the hypothesis we are aressing es not concern a parameter.以及non的情况不是1.要么不是参数 2.要么是参数但不符合条件，所以c我觉得也是错的，感觉只说了一半。

请问，假设检验是不是分参数检验和非参数检验？
