Listed below are the lead concentrations in pig/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 17 ug/g. Assume that the sample is a simple random sample. 21 3 5 4.5 22.5 1 15.5 18.5 4 17 5 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?
