Listed below are the lead concentrations in ug/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 ug/g. Assume that the sample is a simple random sample. 16 5.5 18 18 20 19 15.5 7 15 21.5 0 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: H = 18 pig/g O B. Ho: 1 = 18 pig/g Hy: 1 18 pig/g O C. Ho: H = 18 pig/g OD. Ho: H > 18 pig/g H1: 1 # 18 ug/g H1 : H
