Transcribed Image Text:**Problem Description:**
Consider the hypotheses below:
- \( H_0: \mu \geq 70 \)
- \( H_1: \mu < 70 \)
Given that \( \bar{x} = 64.7 \), \( s = 7.6 \), \( n = 30 \), and \( \alpha = 0.05 \), complete parts a and b below.
**a) What conclusion should be drawn?**
1. **Determine the critical value(s):**
- The critical value(s) is(are) _______.
- *(Round to three decimal places as needed. Use a comma to separate answers as needed.)*
2. **Determine the test statistic \( t_x \):**
- \( t_x = \) _______
- *(Round to two decimal places as needed.)*
3. **What conclusion should be drawn?**
- O A. Do not reject \( H_0 \). There is not sufficient evidence to conclude that \( \mu < 70 \).
- O B. Reject \( H_0 \). There is not sufficient evidence to conclude that \( \mu < 70 \).
- O C. Reject \( H_0 \). There is sufficient evidence to conclude that \( \mu < 70 \).
- O D. Do not reject \( H_0 \). There is sufficient evidence to conclude that \( \mu < 70 \).
**b) Use technology to determine the p-value for this test.**
- \( p\text{-value} = \) _______
- *(Round to three decimal places as needed.)*
