Listed below are the lead concentrations in μg/g measured in different traditional medicines. Use a 0.10 significance level to test the claim that the mean lead concentration for all such medicines is less than 17 μg/g. Assume that the sample is a simple random sample. 19.5 14.5 18 16.5 10 15 5 10.5 12 8 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?
PLEASE ONLY SELECT THE ANSWERS AS SHOWN FOR THE MULTIPLE CHOICE, SUCH AS OPTION 1, 2, ETC.
1)
Listed below are the lead concentrations in μg/g measured in different traditional medicines. Use a 0.10 significance level to test the claim that the mean lead concentration for all such medicines is less than 17 μg/g. Assume that the sample is a simple random sample.
19.5 14.5 18 16.5 10 15 5 10.5 12 8
Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?
A.
H0: μ>17 μg/g
H1: μ<17 μg/g
B.
H0: μ=17 μg/g
H1: μ≠17 μg/g
C.
H0: μ=17 μg/g
H1: μ<17 μg/g
D.
H0: μ=17 μg/g
H1: μ>17 μg/g
2)
Determine the test statistic.
(Round to two decimal places as needed.)
Determine the P-value.
(Round to three decimal places as needed.)
3)
State the final conclusion that addresses the original claim.
(OPTION 1-Reject, OPTION 2- Fail to reject) Ho. There is (OPTION 1-sufficient, OPTION 2-not sufficient) evidence to conclude that the mean lead concentration for all such medicines is (OPTION 1-equal to, OPTION 2-is greater than, OPTION 3-is not, OPTION 4-is less than) 17 μg/g.
