Suppose 216 subjects are treated with a drug that is used to treat pain and 53 of them developed nausea. Use a 0.01 significance level to test the claim that more than 20% of users develop nausea.

Identify the null and alternative hypotheses for this test. Choose the correct answer below.

- A. \( H_0: p > 0.20 \)
       \( H_1: p = 0.20 \)
- B. \( H_0: p = 0.20 \)
       \( H_1: p \neq 0.20 \)
- C. \( H_0: p = 0.20 \)
       \( H_1: p < 0.20 \)
- D. \( H_0: p = 0.20 \)
       \( H_1: p > 0.20 \)

The correct answer is D.

Identify the test statistic for this hypothesis test.
