Listed below are the lead concentrations in μg/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 μg/g. Assume that the sample is a simple random sample. 18 11.5 5.5 8.5 5.5 14 11 6 10.5 15.5
Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?
A.
H0: μ=14 μg/g
H1: μ>14 μg/g
B.
H0: μ=14 μg/g
H1: μ<14 μg/g
Your answer is correct. C.
H0: μ>14 μg/g
H1: μ<14 μg/g
D.
H0: μ=14 μg/g
H1: μ≠14 μg/g
Determine the test statistic.
nothing (Round to two decimal places as needed.)
Determine the P-value?
