Question
You wish to test the following claim \((H_a)\) at a significance level of \(\alpha = 0.02\).

\[ H_0: \mu = 68.9 \]
\[ H_a: \mu > 68.9 \]

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size \( n = 11 \) with mean \( M = 75.8 \) and a standard deviation of \( SD = 5.7 \).

**Questions:**

1. What is the test statistic for this sample? (Report answer accurate to three decimal places.)
   - Test statistic = [ ]

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

**The p-value is...**

- ○ less than (or equal to) \(\alpha\)
- ○ greater than \(\alpha\)

**This test statistic leads to a decision to...**

- ○ reject the null
- ○ accept the null
- ○ fail to reject the null

**As such, the final conclusion is that...**

- ○ There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 68.9.
- ○ There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 68.9.
- ○ The sample data support the claim that the population mean is greater than 68.9.
- ○ There is not sufficient sample evidence to support the claim that the population mean is greater than 68.9.
