Question
The test statistic of \( z = 1.41 \) is obtained when testing the claim that \( p > 0.8 \).

a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed.

b. Find the P-value.

c. Using a significance level of \( \alpha = 0.01 \), should we reject \( H_0 \) or should we fail to reject \( H_0 \)?

- [Link to page 1 of the standard normal distribution table.](#)
- [Link to page 2 of the standard normal distribution table.](#)

a. This is a [  ] test.

b. \( \text{P-value} = \mathbf{\_\_} \) (Round to three decimal places as needed.)

c. Choose the correct conclusion below.

- A. Reject \( H_0 \). There is sufficient evidence to support the claim that \( p > 0.8 \).

- B. Fail to reject \( H_0 \). There is sufficient evidence to support the claim that \( p > 0.8 \).

- C. Reject \( H_0 \). There is not sufficient evidence to support the claim that \( p > 0.8 \).

- D. Fail to reject \( H_0 \). There is not sufficient evidence to support the claim that \( p > 0.8 \).
