Problem

Keiko and Kaitlin each graduated from college last year and got entry-level positions. Keiko got an entry-level position as a chemist with a salary of $59,416, and Kaitlin got an entry-level position as a mathematician with a salary of $78,633.

Last year, the distributions of entry-level salaries were clearly bell-shaped for chemists and for mathematicians. That year, the entry-level salary of chemists had a population mean of $63,000 and a standard deviation of $2200, and the entry-level salaries of mathematicians had a population mean of $71,000 and a standard deviation of $2700.

(a) Find the z-scores of Keiko's entry-level salary as a chemist and Kaitlin's entry-level salary as a mathematician. Round your
answers to two decimal places.
E-score of Keiko's salary: I
E-score of Kaitlin's salary:
(b) Relative to her population, who got the higher salary?
Choose the best answer based on the --scores of the two salaries.
O Keiko
O Kaitlin
O It is unclear who got the higher salary relative to her population
