DESCRIPTIVE STATISTICS = Comparing the relative sizes of data values based on their Z-... 1/5 Keith ai. Van each graduated from college last year and got entry-level positions. Keith got an entry-level position as a chemist with a salary of $54,812, and Ryan got an entry-level position as a mathematician with a salary of $65,607. Last year, the distributions of entry-level salaries were clearly skewed (not approximately symmetric) for chemists and for mathematicians. That year, the entry-level salary of chemists had a population mean of $59,000 and a standard deviation of $2250, and the entry-level salaries of mathematicians had a population mean of $68,000 and a standard deviation of $2100. (a) Find the z-scores of Keith's entry-level salary as a chemist and Ryan's entry-level salary as a mathematician. Round your answers to two decimal places. z-score of Keith's salary: -1.86 E-score of Ryan's salary: -1.14 (b) Relative to his population, who got the higher salary? Choose the best answer based on the z-scores of the two salaries. O Keith Ryan It is unclear who got the higher salary relative to his population
