For each of the -3.3 trials, and in the same sequence in which you entered the freezing points, enter your calculated values for the freezing point depression constant of water. Be sure to use the average value for the freezing point of pure water and the value for the molality of the solution that you entered earlier. Report your values to 3 significant figures # of Trials TMC) Kf (Kelvin kg/mol)
Trial 1: -3.30
Trial 2: -3.90
Trial 3: -3.60

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
