In 2002, the mean age of an inmate on death row was 40.7 years, according to data obtained from the U.S. Department of Justice. A sociologist wondered whether the mean age of a death-row inmate has changed since then. She randomly selects 34 death-row inmates and finds that their mean age is 38.5, with a standard deviation of 10.2.  Does this data indicate that the mean age of death-row inmates has changed significantly since 2002.

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 52 entry level electrical engineers. Their mean salaries were $46,200 and $46,700, respectively. Their standard deviations were $3440 and $4230, respectively. Conduct a hypothesis test at the 5% level...
