Construct a 99​% confidence interval about the mean age of death row inmates?, statistics assignment help

Several years​ ago, the reported mean age of an inmate on death row was 35.4 years. A sociologist wondered whether the mean age of a​ death-row inmate has changed since then. He randomly selects 32 ​death-row inmates and finds that their mean age is 33.6, with a standard deviation of 9.5.

Construct a 99​% confidence interval about the mean age of death row inmates. What does the interval​ imply?

 (_ , _)

(Use ascending order. Round to two decimal places as​ needed.)

What does the interval​ imply?

A. Since the given mean age is in the ​interval, do not reject the null hypothesis.

B. Since the given mean age is in the ​interval, reject the null hypothesis.

C. Since the given mean age is not in the ​interval, reject the null hypothesis.

D. Since the given mean age is not in the ​interval, do not reject the null hypothesis.
