1.5

Answer 1

The z-score of a company employee who makes an annual salary of $28,000 will be -1.5.

How to calculate the z score?

The following can be deduced from the information given:

Raw score = x = 28000

Mean = u = 34000

Standard deviation = 4000

Z = (28000 - 34000)/4000

Z = -6000/4000

Z = -1.5.
