8. Relationships between means, standard deviations, X values, and z-scores The International Average Salary Income Database provides a comparison of average salaries for various professions. The data are gathered from publications and reports obtained directly from government agencies (such as the U.S. Bureau of Labor Statistics) or from the International Labour Organization. Suppose you are told that a computer programmer in Poland who makes $1,338.00 has a z-score of +2.00 relative to other computer programmers in Poland and that the standard deviation of the salary of computer programmers in Poland is $223.00. The average salary, then, for computer programmers in Poland is Suppose you are also told that a computer programmer in Portugal who makes $636.00 has a z-score of -1.25 relative to other computer programmers in Portugal and that the mean of the salary of computer programmers in Portugal is 925. The standard deviation of the salary, then, for computer programmers in Portugal is
