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.
请问我把(1.2-1)/sqrt5 = 0.08944带入带normal distribution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
