Listed below are the lead concentrations in μg/g measured in different traditional medicines. Use a 0.10 significance level to test the claim that the mean lead concentration for all such medicines is less than 16 μg/g. Assume that the sample is a simple random sample. 18 9.5 20 18 3.5 5.5 7.5 13 3 17.5 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? A. H0: μ = 16 μg/g H1: μ > 16 μg/g B. H0: μ = 16 μg/g H1: μ ≠ 16 μg/g C. H0: μ > 16 μg/g H1: μ < 16 μg/g D. H0: μ = 16 μg/g H1: μ < 16 μg/g Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. (1) ----------H0. (2) There is ------------evidence to conclude that the mean lead concentration for all such medicines is (3)--------16 g/g.
