`GRADE`

on the exam.
Find the z-score for `person( 1 )`'s exam grade. Round to two decimal places.

A z-score is defined as the number of standard deviations a specific point is away from the mean.

We can calculate the z-score for `person( 1 )`'s exam grade by subtracting the mean `(\mu)`

from
his grade and then dividing by the standard deviation `(\sigma)`
