+4 Several years ago, the reported mean age of an inmate on death row was
38.7 years. A sociologist wondered whether the mean age of a death-row inmate has changed since then.
He randomly selects 37 death-row inmates and finds that their mean age is 36.9 with a standard deviation of 8.8
Construct a 90% confidence interval about the mean age of death row inmates. What does the interval imply?
Choose the correct hypotheses.
Upper H 0
μ = 38.7
(I've edited this to remove the repeated numbers. I hope it is now clearer, and that I haven't changed the meaning of anything in doing so! Alan)
