Consider a drug testing company that provides a test for marijuana usage. Among 338 tested subjects, results from 28 subjects were wrong (either a false positive or a false negative). Use a 0.10 significance level to test the claim that less than 10 percent of the test results are wrong. Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho p=0.1 H:p<0.1 O B. Ho: p<0.1 H,:p=0.1 OC. Ho p=0.1 H,: p#0.1 O D. Ho p=0.1 H1: p>0.1 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test isO (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Fail to reject H. There is sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong O B. Reject Ho There is not sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. OC. Reject Ho. There is sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. O D. Fail to reject Ho. There is not sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong.

Hi Great Bartleby Team,

I need asap help for this exercise, Please answer all the parts of the exercise. Thanks a lot in advance.

**Hypothesis Testing for Marijuana Usage Test Accuracy** Consider a drug testing company that provides a test for marijuana usage. Among 338 tested subjects, results from 28 subjects were wrong (either a false positive or a false negative). Use a 0.10 significance level to test the claim that less than 10 percent of the test results are wrong. **Identify the null and alternative hypotheses for this test. Choose the correct answer below:** - **A.** \( H_0: p = 0.1 \) \( H_1: p < 0.1 \) - **B.** \( H_0: p < 0.1 \) \( H_1: p = 0.1 \) - **C.** \( H_0: p = 0.1 \) \( H_1: p \neq 0.1 \) - **D.** \( H_0: p = 0.1 \) \( H_1: p > 0.1 \) **Identify the test statistic for this hypothesis test.** The test statistic for this hypothesis test is \(\_\_\_\_\_\_\_\_\_\). *(Round to two decimal places as needed.)* **Identify the P-value for this hypothesis test.** The P-value for this hypothesis test is \(\_\_\_\_\_\_\_\_\_\). *(Round to three decimal places as needed.)* **Identify the conclusion for this hypothesis test.** - **A.** Fail to reject \( H_0 \). There is sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. - **B.** Reject \( H_0 \). There is not sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. - **C.** Reject \( H_0 \). There is sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. - **D.** Fail to reject \( H_0 \). There is not sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong.
