Answer:
The z score is -1.39
Step-by-step explanation:
Taking into account, that the student score is 75 points, the mean score is 83.5 and the standard deviation is 6.1. The z score is calculated as:
[tex]z=\frac{x-m}{s}[/tex]
Where x is the score that the student gets, m is the mean score and s is the standard deviation, so the z score is:
[tex]z=\frac{75-83.5}{6.1}=-1.39[/tex]
