Normal Deviate Z test • • Normal deviate z test formula 𝑍 𝑛𝑜𝑟𝑚 𝑑𝑒𝑣 = 𝑀−𝜇 𝜎 𝑀 • The z value that is obtained can then be referenced against the normal distribution

Portion of the Normal Curve • It is also possible to determine the proportion of the normal curve that is greater than or less than the obtained z value
