### Hypothesis Testing Example

In a test of the hypothesis \( H_0: \mu = 10 \) versus \( H_a: \mu \neq 10 \), a sample of \( n = 50 \) observations possessed mean \( \bar{x} = 10.7 \) and standard deviation \( s = 2.9 \). Find and interpret the p-value for this test.

1. **Step 1: Calculate the test statistic**
   \[
   t = \frac{\bar{x} - \mu_0}{s / \sqrt{n}}
   \]
   where \( \bar{x} = 10.7 \), \( \mu_0 = 10 \), \( s = 2.9 \), and \( n = 50 \).

2. **Step 2: Determine the p-value**
   Calculate the p-value from the test statistic using the appropriate distribution (t-distribution with \( n - 1 \) degrees of freedom).

3. **Next, you are required to fill in the calculated p-value:**
   \[
   \text{The p-value for this test is } \_\_\_\_ . \text{ (Round to four decimal places as needed.)}
   \]

4. **Step 3: Interpret the result. Choose the correct answer below:**
   \[
   \text{A. There is sufficient evidence to reject } H_0 \text{ for } \alpha > 0.09.
   \]
   \[
   \text{B. There is sufficient evidence to reject } H_0 \text{ for } \alpha < 0.09.
   \]
   \[
   \text{C. There is insufficient evidence to reject } H_0 \text{ for } \alpha = 0.15.
   \]
   \[
   \text{D. There is insufficient evidence to reject } H_0 \text{ for } \alpha > 0.09.
   \]

**Explanation:**
- Choice **A** is correctly selected on the screen, indicating that the p-value calculated is greater than 0.09, suggesting that there is sufficient evidence to reject the null hypothesis \( H_0 \) when the significance level \( \alpha \) is greater than 0.09.
- Each choice reflects a possible interpretation of the p-value in relation to the significance level \(
