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 20 µg/g. Assume that the sample is a simple random sample. 20.5 11.5 21.5 18.5 5.5 20 22 15.5 5 21.5 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? OA. H: 20 µg/g H₁: 20 μg/g OC. H₂: 20 µg/g H₁:μ#20 μg/g Determine the test statistic. (Round to two decimal places needed.) Determine the P-value. (Round to three decimal places a needed.) State the final conclusion that addresses the original claim. Ho. There is Reject Fail to reject OB. H₂>20 µg/g H₁: <20 µg/g OD. H₂:20 µg/g H₁:μ>20 μg/g evidence conclude that the mean lead concentration for all such medicines is 20 µg/g

OA. Ho: 20 μg/g H₁:20 µg/g OC. Ho: 20 μµg/g H₁: μ#20 µg/g Determine the test statistic. (Round to two decimal places a needed.) Determine the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. H₂. There is not sufficient OB. Ho: >20 µg/g H₁: 20 µg/g evidence to conclude that the mean lead concentration for all such medicines is sufficient OD. Ho: 20 µg/g H₁: μ>20 µg/g 20 µg/g.
