Clear selection 7. Louisa was explaining to her friend Giselle that two objects, cut from the same
sheet of metal, cannot possibly be the same density because one of the pieces
is significantly larger than the other. She claims that because one of them is so
much heavier than the other, it has more atoms in it and therefore has a different
density. In the space below, remembering that density equals mass divided by
volume, explain why Louisa's thinking is incorrect.

Where are each of the three particles located within the atom?

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.
