Determining Normal Probabilities (VCE SSCE Mathematical Methods): Flashcards

Calculates probability within a specified range

Finds value (percentile) from a given probability

$\mu = 0$ and $\sigma = 1$

Value below which a certain % of observations fall

Leave equal areas in each tail

$1 - \text{Pr}(Z \leq a)$

Equals $\text{Pr}(Z > a)$

$1 - 2\text{Pr}(Z \geq a)$

Each tail: 2.5% (0.025)

You know probability and need to find the value
