18) List below are the lead concentrations in UG/G measure in different traditional medicines. Use a 0.05 significance level to testicle that the mean lead concentration for all such medicines is less than 15 Ug/g. Assume that the sample is a simple random sample19.5, 15, 6, 6.5, 12.5, 13.5, 7, 7, 17, 3.5Assuming all conditions for conducting a hypothesis test are mad what are the normal and alternative hypothesisDetermined to test statisticDetermine the P valueState the final conclusion that addresses the original claim

Listed below are the lead concentrations in pg/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 in less than 15 pg/g. Assume that the sample is a simple random sample. 19.5 15 6 65 125 13.5 7 7 17 3.5 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A.
