Putting it all Together: Argument From Evidence The Law of Conservation of Matter states that matter can not be created, nor destroyed, it merely
changes forms. Your friend, Lisa, does not believe that the law of conservation is true because the
mass of the products is definitely less than the mass of the reactants in the campfire scenario.
Create an argument to support or refute Lisa's claim.
Include:
The initial claim, the evidence to support or refute the claim, and the scientific reasoning for
observed phenomena.
Address any counterclaims posed.
Identify the strengths and weaknesses of claims.

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.
