Example 4
Several years ago, the reported mean age of an inmate on death row was 42.4 years. A sociologist wondered whether the mean age of a death-row inmate has changed since then. He randomly selects 35 death-row inmates and finds that their mean age is 40.6, with a standard deviation of 9.9. Construct a 90% confidence interval about the mean age of death row inmates. What does the interval imply? What is the correct hypothesis?
