Listed below are the lead concentrations in up/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 ug/g. Assume that the sample is a simple random sample. 13 17.5 20 6 9.5 18 17 14 17.5 14 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: H=17 pg/g O B. Ha: [> 17 pg/g Hy : H= 17 ug/g H, : p 17 pg/g
