\fListed below are the lead concentrations in ug/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 13 ug/g. Assume that the sample is a simple random sample. 7.5 18.5 9.5 20.5 4 18 4.5 8 11.5 4.5 0 . . . Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: H = 13 ug/g O B. Ho: H > 13 ug/g H1: H # 13 ug/g H1: H 13 ug/g
