On a recent quiz, the class mean was 72 with a standard deviation of 4.2. calculate the z-score (to 2 decimal places) for a person who received score of 59.

The Z score of the person is -3.09.

Step-by-step explanation:

The standard normal deviate (Z) for a normal distribution is given by

where,
