**Which of the following is the hypothesis test to be conducted?**
- A. \( H_0: p < 0.5 \)
\( H_1: p = 0.5 \)
- B. \( H_0: p = 0.5 \)
\( H_1: p < 0.5 \)
- C. \( H_0: p > 0.5 \)
\( H_1: p = 0.5 \)
- D. \( H_0: p = 0.5 \)
\( H_1: p \ne 0.5 \)
- E. \( H_0: p \ne 0.5 \)
\( H_1: p = 0.5 \)
- F. \( H_0: p = 0.5 \)
\( H_1: p > 0.5 \) ✅
