Transcribed Image Text:### 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.
