Use a 0.05 significance level to test the claim that more than 20% of users develop nausea.**Hypothesis Identification:**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 $ $H_1$: $ p = 0.20 $ - **D.** $H_0$: $ p = 0.20 $ $H_1$: $ p \neq 0.20 $**Test Statistic Identification:**Identify the test statistic for this hypothesis test.The test statistic for this hypothesis test is $ \Box $ (Round to two decimal places as needed.)**P-Value Identification:**Identify the P-value for this hypothesis test.The P-value for this hypothesis test is $ \Box $ (Round to three decimal places as needed.)**Conclusion Identification:**Identify the conclusion for this hypothesis test.- **A.** Fail to reject $H_0$. There is sufficient evidence to warrant support of the claim that more than 20% of users develop nausea.- **B.** Fail to reject $H_0$. There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea.- **C.** Reject $H_0$. There is sufficient evidence to warrant support of the claim that more than 20% of users develop nausea.- **D.** Reject $H_0$. There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea.---**Graphical and Diagram Explanation:**There are no graphs or diagrams included in this text.---This problem involves hypothesis testing for a population proportion.
