## Statistics Tutorials – Z Scores

Assume that $$X$$ has a normal distribution, with mean $$\mu$$ and standard deviation $$\sigma$$. This is typically written as \ Then, the Z-score associated to $$X$$ is defined as \ Example: Consider the random variable $$X$$, which as a normal ...

## Properties of the Standard Normal Distribution

The normal distribution probability is specific type of continuous probability distribution. A normal distribution variable can take random values on the whole real line, and the probability that the variable belongs to any certain interval is ...

## Calculation of Conditional Probabilities

Let $$A$$ and $$B$$ be events. The conditional probability is defined as \ as long as $$Pr(B) \ne 0$$. This conditional probability can be interpreted as the probability that A happens assuming that we know that B is true. In other words,...
