### Hypothesis Testing for Lead Concentration in Traditional Medicines **Data:** Listed below are the lead concentrations in μg/g measured in different traditional medicines: - 19.5, 6.5, 5.5, 2.5, 3.5, 5.5, 14, 18, 3, 9 **Objective:** Use a 0.05 significance level to test the claim that the mean lead concentration for all such medicines is less than 13 μg/g. Assume that the sample is a simple random sample. **Hypothesis Testing:** **Determine the null and alternative hypotheses:** - **Option A:** - \( H_0: \mu > 13 \, \mu g/g \) - \( H_1: \mu < 13 \, \mu g/g \) - **Option B:** - \( H_0: \mu = 13 \, \mu g/g \) - \( H_1: \mu > 13 \, \mu g/g \) - **Option C:** - \( H_0: \mu = 13 \, \mu g/g \) - \( H_1: \mu \neq 13 \, \mu g/g \) - **Option D (Correct Choice):** - \( H_0: \mu = 13 \, \mu g/g \) - \( H_1: \mu < 13 \, \mu g/g \) **Determine the test statistic:** - Round to two decimal places as needed. **Note:** - Ensure the assumptions for hypothesis testing are satisfied before proceeding. - Calculate the test statistic to verify the hypothesis.
