Question
One year, the mean age of an inmate on death row was 40.5 years. A sociologist wondered whether the mean age of a death-row inmate has changed since then. She randomly selects 32 death-row inmates and finds that their mean age is
39.4, with a standard deviation of 9.5. Construct a 95% confidence interval about the mean age. What does the interval imply?
