Listed below are the lead concentrations in µg/g measured in different traditional medicines. Use a 0.05 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. 21.5 21.5 4 16.5 14 10.5 4 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: μ = 18 µg/g H₁: μ> 18 μg/g O C. Ho: μ = 18 µg/g H₁: μ# 18 μg/g 16.5 18 5 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 Reject Fail to reject evidence to conclude that the mean lead concentration for all such medicines is OB. Ho: μ-18 µg/g H₁: μ< 18 µg/g OD. Ho: μ> 18 µg/g Hy: μ < 18 μg/g 18 µg/g.
