# Hypothesis Testing and P-Values

The P-value for a hypothesis test is given as 0.0471. Use this P-value to decide whether to reject the null hypothesis \( H_0 \) when the level of significance is:

- (a) \( \alpha = 0.01 \)
- (b) \( \alpha = 0.05 \)
- (c) \( \alpha = 0.10 \)

## (a) \( \alpha = 0.01 \)
**Do you reject or fail to reject \( H_0 \) at the 0.01 level of significance?**

- A. Reject \( H_0 \) because the P-value, 0.0471, is greater than \( \alpha = 0.01 \).
- B. Reject \( H_0 \) because the P-value, 0.0471, is less than \( \alpha = 0.01 \).
- C. Fail to reject \( H_0 \) because the P-value, 0.0471, is greater than \( \alpha = 0.01 \).
- D. Fail to reject \( H_0 \) because the P-value, 0.0471, is less than \( \alpha = 0.01 \).

## (b) \( \alpha = 0.05 \)
**Do you reject or fail to reject \( H_0 \) at the 0.05 level of significance?**

- A. Reject \( H_0 \) because the P-value, 0.0471, is less than \( \alpha = 0.05 \).
- B. Fail to reject \( H_0 \) because the P-value, 0.0471, is greater than \( \alpha = 0.05 \).
- C. Fail to reject \( H_0 \) because the P-value, 0.0471, is less than \( \alpha = 0.05 \).
- D. Reject \( H_0 \) because the P-value, 0.0471, is greater than \( \alpha = 0.05 \).

## (c) \( \alpha = 0.10 \)
**Do you reject or fail to reject \( H_0 \) at the 0.10 level of significance?**

- A. Fail to reject \( H_0 \
