One year, the mean age of an inmate on death row was 41.5 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 40.2, with a standard deviation of 9.1. Construct a 95% confidence interval about the mean age. What does the interval imply? E Click the icon to view the table of critical t-values. Choose the correct hypotheses. Ho: H 41.5 * 41.5 (Type integers or decimals. Do not round.) Construct a 95% confidence interval about the mean age. With 95% confidence, the mean age of a death row inmate is between years and years. (Round to two decimal places as needed.)
