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 17 pg/g. Assume that the sample is a simple random sample. 15.5 10 8 12.5 6 19.5 17 19 21.5 19.5 . . . Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: H = 17 ug/g O B. Ho: H = 17 pg/g H1: H 17 pg/g O C. Ho: H = 17 ug/g O D. Ho: H > 17 pg/g H1: H # 17 ug/g H1: H
