The annual salaries of all employees at a financial company are normally distributed with a mean Mu = $34,000 and a standard deviation Sigma = $4,000. What is the z-score of a company employee who makes an annual salary of $28,000? –5 –3. 5 –1. 5 1. 5.

z-score of an employee making an annual salary of $28000 is -1.5.

It is given that,

mean μ = $34000

standard deviation σ = $4000

salary x = $28000

z-score is a numerical measurement that describes a value's relationship to the mean of values.

formulae to calculate z-score = (x - μ)/σ

so, z-score = (28000-34000)/4000

z = -1.5

therefore, the z-score of an employee making an annual salary of $28000 is -1.5.
