Listed below are the lead concentrations in μ​g/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 μ​g/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 μ​g/g
H1​: μ>14 μ​g/g
B.
H0​: μ=14 μ​g/g
H1​: μ<14 μ​g/g
Your answer is correct. C.
H0​: μ>14 μ​g/g
H1​: μ<14 μ​g/g
D.
H0​: μ=14 μ​g/g
H1​: μ≠14 μ​g/g
Determine the test statistic.
nothing ​(Round to two decimal places as​ needed.)
Determine the P-value?
