Extracted text: Listed below are the lead concentrations in pg/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 16 µg/g Assume that the sample is a simple random sample. 10 3.5 8 6.5 15.5 12 9 11 20 15.5 D Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?
