**Hypothesis Testing for Drug Test Accuracy****Scenario Description:**Consider a drug testing company that provides a test for marijuana usage. Among 268 tested subjects, results from 28 subjects were wrong (either a false positive or a false negative). Use a 0.05 significance level to test the claim that less than 10 percent of the test results are wrong.**Problem Statement:**Identify the null and alternative hypotheses for this test. Choose the correct answer below.**Options:**A. \( H_0: p = 0.1 \) \( H_1: p \neq 0.1 \) B. \( H_0: p = 0.1 \) \( H_1: p < 0.1 \) C. \( H_0: p > 0.1 \) \( H_1: p \leq 0.1 \) D. \( H_0: p < 0.1 \) \( H_1: p = 0.1 \) **Correct Answer:**- **B.** \( H_0: p = 0.1 \) \( H_1: p < 0.1 \) **Note:**Identify the test statistic for this hypothesis test.
