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 18 µg/g. Assume that the sample is a simple random sample. 14.5 20 20.5 7 10 16 10 13.5 21.5 14.5 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? OA. Ho: μ= 18 µg/g OB. Ho: μ> 18 µg/g H₁: μ#18 μg/g Hy: μ < 18 μg/g OC. Ho: μ= 18 µg/g H₁: μ> 18 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 O D. Ho: μ= 18 µg/g H₁: μ< 18 μg/g evidence to conclude that the mean lead concentration for all such medicines is 18 µg/g.
