Submit test Question 13 of 13 This question: 1 point(s) possible One year, the mean age of an inmate on death row was 38.6 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 36.7, with a standard deviation of 9 7. Construct a 95% confidence interval about the mean age.
