Carry out significant test to determine where the 6 measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dL.

A reference solution used as a lab reagent is purported to have a concentration of 5 mg/dL. 6 samples are taken from this solution and following concentration are as recorded: {5.32, 4.88, 5.10, 4.73, 5.15, 4.75} mg/dL. The 6 measurements are assumed to have a standard deviation of 0.2, normal distribution, and mean concentration equal to the true concentration of the solution.
