## Hypothesis Testing at α = 0.05 Significance Level

**Objective:**
Conduct a hypothesis test to determine whether \( p_1 \neq p_2 \). The sample data are as follows: \( x_1 = 28 \), \( n_1 = 255 \), \( x_2 = 38 \), \( n_2 = 302 \). Assume simple random sampling.

### Steps:

### (a) Determine the Null and Alternative Hypotheses:
Choose the correct pair:
- **A.** \( H_0: p_1 = p_2 \) versus \( H_1: p_1 < p_2 \)
- **B.** \( H_0: p_1 = p_2 \) versus \( H_1: p_1 \neq p_2 \)
- **C.** \( H_0: p_1 = p_2 \) versus \( H_1: p_1 > p_2 \)
- **D.** \( H_0: p_1 = 0 \) versus \( H_1: p_1 = 0 \)

### (b) Test Statistic \( z_0 \):
Calculate and fill in the test statistic value.
- \( z_0 = \_ \) (Round to two decimal places as needed.)

### (c) P-value:
Determine and input the P-value.
- P-value = \_ (Round to three decimal places as needed.)

### Conclusion:
Choose the correct conclusion about the null hypothesis:
- **A.** Do not reject the null hypothesis because there is sufficient evidence to conclude that \( p_1 > p_2 \).
- **B.** Reject the null hypothesis because there is sufficient evidence to conclude that \( p_1 \neq p_2 \).
- **C.** Do not reject the null hypothesis because there is not sufficient evidence to conclude that \( p_1 \neq p_2 \).
- **D.** Reject the null hypothesis because there is not sufficient evidence to conclude that \( p_1 < p_2 \).
