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 14 pg/g. Assume that the sample is a simple random sample. 13.5 18 4 5.5 2.5 15.5 10 3 4 19 0 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: H= 14 pg/g O B. Ho: H= 14 pg/g H1 : p > 14 pg/g H1: H = 14 pg/g O C. Ho: H > 14 pig/g O D. Ho: H= 14 pig/g H1: H = 14 pg/g H1: p# 14 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 14 pg/g
