You wish to test the following claim (\(H_a\)) at a significance level of \(\alpha = 0.05\).

\[
H_0: \mu = 72.5
\]

\[
H_a: \mu \neq 72.5
\]

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size \(n = 14\) with mean \(M = 81.7\) and a standard deviation of \(SD = 15.6\).

What is the test statistic for this sample? (Report answer accurate to three decimal places.)

\[ \text{test statistic} = \boxed{\phantom{000}} \]

What is the p-value for this sample? (Report answer accurate to four decimal places.)

\[ \text{p-value} = \boxed{\phantom{0000}} \]

**Hypothesis Testing Options**

This section guides you through making a decision based on the test statistic:

- [ ] Reject the null
- [ ] Accept the null
- [ ] Fail to reject the null

**Final Conclusion Options**

Based on the decision, choose the appropriate conclusion:

- [ ] There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 72.5.
- [ ] There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 72.5.
- [ ] The sample data support the claim that the population mean is not equal to 72.5.
- [ ] There is not sufficient sample evidence to support the claim that the population mean is not equal to 72.5.
