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 is less than 19 ug/g. Assume that the sample is a simple random sample. 17.5 20 5 20.5 17 5 16 4 195 5.5 16 22 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: H = 19 pg/g O B. Ho H= 19 ug/g H, u 19 ugg OD. Ho H = 19 pg/g H1 : u 19 pg/g Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. (Round to three decimal places as needed ) State the final conclusion that addresses the original claim. Ho. There is evidence to conclude that the mean lead concentration for all such medicines is 19 pg/g
