Sheila conducts an investigation to see how the amount of salt dissolved in water affects the density of the water. which statement best describes the correct plan for her procedure?

A list of statements is not proved, but Sheila is definitely conducting an experiment. An experiment consists of someone coming up with a hypothesis and then testing to see if the hypothesis is true. Likely, she will take cups of water with varying levels of salt. Then, she will float the same object in the water, and measure its buoyancy to determine the density.
