The standard normal distribution Z~N(0,1) – Using tables or calculator

The standard normal distribution Z~N(0,1) is very important as I showed you previously, all normal distributions can be transformed to it. From this we then evaluate probabilities. In this video I show you how we can use tables to calculate probabilities of being less than or greater than various z values.

Some calculators offer this function and I have included a video on how the Casio fx-991ES Plus handles this and it is allowed in exams.
