Question

One year, the mean age of an inmate on death row was 41.7 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 39.9, with a standard deviation of 9.3. Construct a 95% confidence interval about the mean age. What does the interval imply? H0: H1: Lower bound: Upper bound:
