问题如下：
A random draw from an N(1,5) distribution is 1.2. If this was generated using the inverse of the cumulative distribution approach, what is the original draw from the U(0,1) distribution?
解释：
Essentially, the question is to determine the cumulative distribution up to 1.2 on an N(1,5) distribution. This can be done with the Excel function NORMDIST(1.2,1,sqrt(5),True) and returns the value 0.535.
老师好，N（1.2）的意思是正态分布1.2的点？

请问我把(1.2-1)/sqrt5 = 0.08944带入带normstribution的z score table里面找表里面的值是0.08944找的跟答案查很多 错在哪里了
如下图您好，请问考试的时候如果出类似的题目怎么算出来X的值呢？反函数是如何运算的呢？
