The mean salary of employees at a company is $32,500,with a standard deviation of $2,500. Calculate the z-score for an employee who makes $38,750. b. What does this Z-score tell you? According to Chebyshev's Theorem, what percent of employees have salaries between $26,250 and $38,750? d. According to the empirical rule; what percent of employees have salaries that are within $5,000 of the mean? Suppose that the distribution of annual salaries is bell-shaped: Would a salary of $42,000 be considered an outlier? Why or why not?
