Listed below are the lead concentrations in µg/g measured in different traditional medicines. Use a 0.01 significance level to test the claim that the mean lead concentration for all such medicines is less than 15 µg/g. Assume that the sample is a simple random sample. 3.5 7 21.5 8 16.5 14.5 21 5.5 5 6 CID Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? OA. Ho: 15 µg/g OB. Ho: > 15 µg/g H₁: μ> 15 µg/g H₁: μ< 15 µg/g OC. Ho: 15 µg/g O D. Ho: 15 µg/g H₁: μ#15 µg/g H₁: μ< 15 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. Ho. There is 15 µg/g. evidence to conclude that the mean lead concentration for all such medicines is
