Help! Thank you

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 37 9, with a standard deviation of 8 5. Construct a 95% confidence interval about the mean age. What does the interval imply? Click the icon to view the table of critical t-values Choose the correct hypotheses Ho H1 OA (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.) What does the interval imply? O A. Since the mean age from the earlier year is contained in the interval, there is sufficient evidence to conclude that the mean age had changed O B. Since the mean age from the earlier year is contained in the interval, there is not sufficient evidence to conclude that the mean age had changed O C. Since the mean age from the earlier year is not contained in the interval, there is sufficient evidence to conclude that the mean age had changed O D. Since the mean age from the earlier year is not contained in the interval, there is not sufficient evidence to conclude that the mean age had changed
