4 c) Consider the following example. An experienced forensic toxicologist tests the abilities of two trainees[A and B) to perform determinations of blood alcohol concentrations (BAC] on an external whole blood control sample reported to contain 0 08 /dL ethanol While evaluating the results, the examiner was not expecting to observe values under 0.070 g/dL and suspects that all the values under 0.070 g/dL may be outliers. He asks you to identify potential aberrant values and perform a formal statstical analysis at a-0.05 to verify if these values can be considered outliers and consequently removed from the datasets Has Trainee B collected outlier values that should be rejected? The calculated value of 0.11 exceeds the Qcrit of 0.05 and therefore Trainee B should consider rejecting this aberrant A value. The calculated value of 0.11 does not exceed the Qcrit of 0.477 and therefore Trainee B should consider rejecting this B aberrant value. C The calculated value of 0.11 does not exceed the Qcrit of 0,477 and therefore Trainee B should not remove any values. The calculated value of 1.0 exceeds the Qcrit of 0.477 and therefore Trainee B should consider rejecting this aberrant D value
