Assume that are testing the claim that the mean age of the prison population in one city is less than 26 years. Sample data are summarized as n = 25, x = 24.4 years, and s 9.2 years. Use a significance level of a = 0.05. Use the given information to answer the questions. 1) Calculate the test statistics. Round to 3 decimal places. (You must show how you set up and calculate the test statistics. Only having calculator work will not count for the test statistics.) 1) 2) Find the p-value and make a decision (reject or fail to reject the null hypotheses). Round each value to 3 decimal places. (You may use Excel or a calulator to find the p-value, but you must write what you input into Excel/calculator below) 2)

Please answer for question #2.
![**Hypothesis Testing for Mean Age of Prison Population**
Assume that you are testing the claim that the mean age of the prison population in one city is less than 26 years. The sample data are summarized as follows:
- Sample size (n) = 25
- Sample mean (\(\bar{x}\)) = 24.4 years
- Sample standard deviation (s) = 9.2 years
Use a significance level of \(\alpha = 0.05\). Use the given information to answer the questions below.
1. **Calculate the Test Statistic:**
- Round to 3 decimal places.
- You must show how you set up and calculate the test statistics. Only having calculator work will not count for the test statistics.
