QuestionSuppose 234 subjects are treated with a drug that is used to treat pain and 54 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. $H_{0}: p>0.20$ $H_{1}: p=0.20$ c. $H_{0}: P=0.20$ $\mathrm{H}_{1}: \mathrm{p}<0.20$ D. $H_{0}: p=0.20$ $H_{1}: p \neq 0.20$
Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is $\square$ $\square$. (Round to two decimal places as needed.).
