Ok so I am having difficulty understand the concept behind standard normal distribution probabilities, in the questions I am getting a graph and a table FILLED with numbers, top header column has values from 0.01 to 0.09 and on left I have 0.0 to 3.8! and the questions are like :
i) P(Z<1.5)= etc.
Now I do not get what they mean by calculating the area at the bottom of the curve (NOT sure what the curve represents!) to the left, so please when explaining use an example and use simple terminology
