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 17 ug/g. Assume that the sample is a simple random sample. 11 19.5 6.5 4.5 19.5 9.5 6.5 19 19 7.5 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: p = 17 pg/g OB. Ho: H = 17 pig/g H1 : p 17 ug/g H1: > 17 pg/g HiEp
