Amy and Jenny each graduated from college last year and got entry-level positions. Last year, the distributions of entry-level salaries were clearly skewed (not approximately symmetric) for software engineers and for nurses. That year, the entry-level salaries of software engineers had a population mean of $68,000 and a standard deviation of $2100, and the entry-level salaries of nurses had a population mean of $59,000 and a standard deviation of $2250. Last year, Amy got an entry-level position as a software engineer with a salary of $65,607, and Jenny got an entry-level position as a nurse with a salary of $54,812. (a) Find the z-scores of Amy's entry-level salary as a software engineer and Jenny's entry-level salary as a nurse. Round your answers to two decimal places. X 5 ? z-score of Amy's salary: z-score of Jenny's salary: (b) Relative to her population, who got the higher salary? Choose the best answer based on the z-scores of the two salaries. O Amy X 5 ? O Jenny O It is unclear who got the higher salary relative to her population
