The annual salaries of all employees at a financial company are normally distributed with a mean mc014-1.jpg = $34,000 and a standard deviation mc014-2.jpg = $4,000. what is the z-score of a company employee who makes an annual salary of $28,000?

The z-score of a data is calculated through the equation,
                          z-score = (x - m)/d
where x is the given value, m is the mean, and d is the standard deviation. Substituting the known values,
                          z-score = (28,000 - 34000) / 4,000
                          z-score = -1.5
Thus, the z-score of the 28,000 is -1.5.
