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 11 ug/g. Assume that the sample is a simple random sample. 22 2.5 17 8 6 6 5 9 42 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A.
