Extracted text: Listed below are the lead concentrations in µg/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 13 ug/g. Assume that the sample is a simple random sample. 19.5 6.5 5.5 2.5 3.5 5.5 14 18 3 9 0 .....
