You can generate the tables, for example, by evaluating an expression for a sequence of different parameter values.
This makes a table with values of x running from 0 to 1 in steps of 0.
However, constructing these queries by hand gets a little cumbersome, so I've created some widgets to make it easier.
This value for z is also marked on the graph with the red line, and you can. I found these values using Wolfram Alpha. If you use a regular CAS-enabled calculator and plug in the command: Your result is the probability of a z-score between andnot between and ?i+standard+deviations+above+the+mean Type Before calculators, people looked stuff like this up on charts.
