Question

A college student is interested in investigating the claim that students who graduate with a master’s degree earn higher salaries, on average, than those who finish with a bachelor’s degree. She surveys, at random, 36 recent graduates who completed their master’s degrees, and finds that their mean salary is $⁢32,400 per year. The standard deviation of annual salaries for the population of recent graduates who have master’s degrees is known to be $1800. She also surveys, at random, 45 recent graduates who completed their bachelor’s degrees, and finds that their mean salary is $⁢31,600 per year. The standard deviation of annual salaries for the population of recent graduates with only bachelor’s degrees is known to be $2800. Test the claim at the 0.01 level of significance. Let recent graduates with a master's degree be Population 1 and let recent graduates with a bachelor's degree be Population 2.
