She surveys, at random, 36 recent graduates who completed their master's degrees, and finds that their mean salary is $35,000 per year. The standard deviation of annual salaries for the population of recent graduates who have master's degrees is known to be $3400. She also surveys, at random, 48 recent graduates who completed their bachelor's degrees, and finds that their mean salary is $34,100 per year. The standard deviation of annual salaries for the population of recent graduates with only bachelor's degrees is known to be $1100. Test the claim at the 0.10 level of significance.
