Listed below are the lead concentrations in ug/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 pig/g. Assume that the sample is a simple random sample. 10 3 9.5 2.5 17.5 6.5 18 22 9 19 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: H > 15 ug/g O B. Ho: H = 15 pig/g Hy: H 15 ug/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 evidence to conclude that the mean lead concentration for all such medicines is 15 pig/g. Reject Fail to reject
