Mean entry-level salaries for college graduates with mechanical engineering
degrees and electrical engineering degrees are believed to be approximately the
same. A recruiting office thinks that the mean mechanical engineering salary is
actually lower than the mean electrical engineering salary. The recruiting office
randomly surveys 50 entry level mechanical engineers and 58 entry level electrical
engineers. Their mean salaries were $46,300 and $46,800, respectively. Their
standard deviations were $3450 and $4230, respectively. Conduct a hypothesis test
at the 5% level to determine if you agree that the mean entry- level mechanical
engineering salary is lower than the mean entry-level electrical engineering salary.
Let the subscript m =

State the distribution to use for the test. (Enter your answer in the
