A student is creating a model of space and wants to include the Earth, the Milky Way galaxy, the universe, and the solar system. How should the student scale the components of the model to make an accurate model? Select the
FOUR statements that apply.
A)
The universe should be the largest component of the model.
B)
The Earth should be a smaller component within the solar system.
C)
The solar system should be scaled smaller than the Milky Way galaxy.
D)
The solar system should be larger than the Earth but not larger than the
Milky Way
E)
The Milky Way should be larger than the Earth but smaller than the solar
system.

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.
