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 18 ug/g. Assume that the sample is a simple random sample. 18 4.5 6.5 10 15.5 22 13.5 8.5 17 18 .... Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: = 18 ug/g Hp> 18 ug/g O B. Ho: = 18 µg/g H: µ#18 µg/g OC. Ho =18 µg/g H:<18 ug/g OD. Ho: u> 18 pg'g H: µ< 18 pg/g Determine the test statistic. 1 (Round to two decimal places as needed.) Determine the P-value. 1 (Round to three decimal places as needed.) State the final conclusion that addresses the original claim
