In 2010, a sociologist randomly selected 20 death-row inmates and found that sample mean age was 38.9 years with sample standard deviation of 9.6 years. A 90 percent confidence interval estimate for the average age of all death-row inmates in 2010 is to be constructed. a. The confidence interval is b. Conclusion: (1 answer) i. We can state with 90 percent confidence that for 2010 the sample mean age of 20 death-row inmates is in the interval constructed. ii. We can state with 90 percent confidence that for 2010 the mean age of all death-row inmates is in the interval constructed iii. There is a 90 percent chance that for 2010 age of any death-row inmate is in the interval constructed iv. We can state with 90 percent confidence that for 2010 ages of 20 death-row inmates lie in the interval constructed c. In 2002, according to the information provided by U.S. Department of Justice, the mean age of all inmates on death row was 40.7 years. Based on the interval constructed, we can conclude with 90 percent confidence, that average age of death-row inmates in 2010
