Listed below are the lead concentrations in 1113/9 measured in different traditional medicines. Use a 0.05 signicance level to test the claim that the mean lead concentration for all such medicines is less than 14 pig/g. Assume that the sample is a simple random sample. 12 3 12 22.5 10.5 9 7 10.5 12.5 SD Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?
