Also determine the test statistic and the P value State the final conclusion that addresses the original claim. 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 15 μg/g. Assume that the sample is a simple random sample.Concentrations: 3.5, 13.5, 9, 17, 17, 9.5, 22, 3, 8.5, 16.5Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?A. \(H_0: \mu = 15 \, \text{μg/g}\) \(H_1: \mu \neq 15 \, \text{μg/g}\)B.\(H_0: \mu = 15 \, \text{μg/g}\) \(H_1: \mu > 15 \, \text{μg/g}\)C.\(H_0: \mu > 15 \, \text{μg/g}\) \(H_1: \mu < 15 \, \text{μg/g}\)D.\(H_0: \mu = 15 \, \text{μg/g}\) \(H_1: \mu < 15 \, \text{μg/g}\)
