**Statistical Analysis:**
**(a)** Select the appropriate set of hypotheses for a two-tailed test aimed at checking for a zero slope:
- a. \(H_0: \beta_1 \geq 0 \) vs. \(H_1: \beta_1 < 0\)
- b. \(H_0: \beta_1 \leq 0 \) vs. \(H_1: \beta_1 > 0\)
- c. \(H_0: \beta_1 = 0 \) vs. \(H_1: \beta_1 \neq 0\)
Which option is correct?
- O a
- O b
- O c
**(b-1)** Determine the p-value (round your answer to four decimal places):
- **p-value:** [Input Box]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb7b9bc12-9bec-475d-bc99-e13d2a9b76e2%2F0943dc9f-ff8b-4915-8bed-62efacb40927%2Fcsjegag_processed.jpeg&w=3840&q=75)
